Antennas often designed in isolated or ideal conditions. But antenna performance can be very different when mounted on realistic and complex platforms. Antenna radiation distortion, reduced antenna efficiency, antenna to antenna coupling, multipath fading are just some of the issues caused by the presence of a complex platform with multiple antennas.
 Using ANSYS HFSS and ANSYS HFSS SBR (Savant) is the solution to a reliable wireless product in realistic environment. HFSS is a FEM tool to design and optimize the antenna and HFSS SBR uses Shooting and Bouncing Ray technique to improve integrated antenna performance on electrically large problems. HFSS SBR takes antenna simulation results from HFSS and provides fast EM analysis of the installed antenna on electrically large platforms.Simulation with HFSS and HFSS SBR:
  • Design and optimize the antenna in HFSS
  • Predict installed antenna performance in HFSS SBR
The figure shows an example of antenna integration on electrically large platform. The 2.3 GHz UHF blade antenna designed and solved in HFSS and the near-field results are imported to HFSS SBR. Then, the far-filed patterns and near-field distributions are computed on the electrically large platform.

Tech Tip

Supercharge your system simulations with the ANSYS MATLAB Toolbox

kaan-80x80One of the most exciting features in the latest release is something that’s not getting much publicity: running MAPDL (or ANSYS Classic) as a headless server. Okay, I can see why people may not be too excited by that but it allows you to run Mechanical APDL with whatever user interface you want, for example – MATLAB. With the MATLAB toolbox you can to run ANSYS, the number one FEA solver in the world, like any other module in MATLAB. This opens up all kinds of possibilities for co-simulation with ANSYS and MATLAB, taking your integrative and system simulations to the next level.

This is not just a more sophisticated way to send batch files to Ansys MAPDL, you can send commands and receive output from a running Ansys FEA solver:

>> mapdl.executeCommandToString('asel,s,mat,,6')

ans =

SELECT       FOR ITEM=MAT  COMPONENT=\n  IN RANGE         6 TO          6 STEP          1\n\n

You can interrogate parameters:

>> str = mapdl.executeCommandToString('*get,max_x,node,,mxloc,x')

str =

*GET MAX_X FROM NODE ITEM=MXLO X VALUE= 500.000000

>> exp = 'VALUE= ([^\s]+)'

exp =

VALUE= ([^\s]+)

>> m = regexp(char(str),exp,'tokens')

m =

{1x1 cell}

>> str2double(char(m{:}))

ans =

500

You can execute commands using Matlab control logic:

 >> loads

loads = 

1x2 struct array with fields:

 cmsel
 val

>> for elem = loads
mapdl.executeCommandToString(strcat('d,', elem.cmsel,',uy,',num2str(elem.val)))

ans =

SPECIFIED CONSTRAINT UY FOR PICKED NODES\n REAL= 300.000000 IMAG= 0.00000000

ans =

SPECIFIED CONSTRAINT UY FOR PICKED NODES\n REAL= 0.00000000 IMAG= 0.00000000

Writing data files is still handled by batch files but MATLAB easily reads and works with comma separated data files:

>> type('to_outf.inp')

*cfopen,outputs,csv
*vwrite,
("plwk_top, plwk_bot")
*vwrite,plwkData(1,1), plwkData(1,2)
(E16.8, "," E16.8)
*cfclos

>> mapdl.executeCommand('/inp,to_outf,inp')

>> tab = readtable('outputs.csv')

tab =

plwk_top plwk_bot
________ ________

0.013099 0.010709
0.025962 0.021216

And of course there are all the plotting and visualization functionality that you are used to:

bar3(table2array(tab))

Dramatic Changes in Sports

MaryamNemaziePicFor you sports lovers out there, not only can you watch a Warriors game, you can also run simulations in sports. As many of you already know, simulations are needed everywhere, especially in the world of sports. Whether to shave off a few seconds from an Olympic record time or to minimize the risk of injuries, ANSYS simulation software is advantageous in the sports arena and gives teams the competitive edge they need to destroy the competition, while maximizing safety.

With the recent release of Concussion starring Will Smith, this expose highlighted the brain damage many football players suffer from due to repeated blows to the head. How can simulations in sports alleviate such tragedies?  The following white paper, Dramatic Changes in Sports: The Contribution of Engineering Simulation, examines how ANSYS simulation technology is utilized in various sports ranging from sailing to badminton.  Simulations in sports helps better understand the activity, improve the performance of the equipment, and reduce the risk of injuries.

Why are Simulations in Sports a Necessity?

Sports professionals and coaches always explore ways to enhance performance and maximize safety. Engineering simulation “is a proven technology able to predict the behavior of a device or an athlete, or a system comprising the athlete, devices and equipment, under specific conditions. Through computer-based modeling, it is possible to determine and understand how influential parameters impact athletic performance, or minimize or amplify injury. By varying these influential conditions and predicting the consequences of these modifications, equipment designers can select the best set of conditions to optimize performance and reduce injury. In addition, sporting goods manufacturers can release these improved goods to market faster and at a lower cost.” Sounds interesting? Click here to read more!

Let’s look at an example of how a simulation would be extremely beneficial. Did you know that our very own Dr. Metin Ozen loves to sail? If he wanted to conduct a simulation before his next sailing adventure, he could use ANSYS CFX to analyze the flow around the modern upwind sails, showing the design procedure from surface definition to grid generation and visualization of the results with the streamlines. Next time you are here at Ozen Engineering for a meeting or a training, ask Dr. Ozen about his sailing adventures in Turkey and the San Francisco Bay.

Ozen Engineering Newsletter – April 2016

Message from your Channel Partner 

 

metinIt is April already, time to file taxes if you have not already done so! For us, it is also the start of a new quarter along with ANSYS certification. As I may have mentioned this in the past, it is very important for an engineering software company like ANSYS to have quality control for the simulation software products. I have been in this industry for almost 35 years and I have observed that ANSYS has the best quality control among the competition.

What does quality control mean for the end user? It means that we can rely on our FEA & CFD results (provided that boundary conditions are accurate) because ANSYS software tools have been verified and validated. One of the reasons why ANSYS has moved to the #1 position in this industry is the fact that ANSYS has the best quality control. As part of the quality control procedures at ANSYS, the channel partners need to go through a “certification” process with every new release! This certification is done for not only technical but also for sales personnel. So, starting in April through the end of June, we will also be going through “certification” to be able to service our clients, provide them with best support, and give them the most accurate information about ANSYS software products. So, welcome to April, please rest assure that ANSYS is the best engineering simulation software in the market and that we are doing our best to serve you in the most efficient way possible. Please let me know if/how I can be of help with ANSYS software. Have a great April!

Tech Tip

Force Based Submodeling 

CanOzcan_VesikalikEven with today’s increased computing power and optimized software, submodeling is a powerful technique to perform analysis on detailed regions of assemblies. Recent versions of ANSYS Mechanical software have easy to use implementation for submodeling, where one can perform cut boundary interpolations all in Workbench environment, without the need of writing good old APDL code.
Submodeling in ANSYS Mechanical (and APDL) is based on interpolation displacements from global level to submodel level at cut boundaries. This approach comes with the assumption that the stiffness of the submodel region does not differ much in stiffness from the global model. This assumption holds most of the time. However, there are cases where one would like to apply structural loads from global model, rather than the displacements. This is especially a requirement when the stiffness of the model is reduced in the modeled sub region. The technique can be also called “Force Based Submodeling”. Below is a naïve implementation of force based submodeling for solid-to-solid case.

Can Pic 1

Need: We would like to apply the force being carried by supports in a submodel, rather than performing a displacement based submodel. The design of the support is changed such that it will invalidate global displacement results. Therefore we propose a way to extract reaction forces at cut boundaries rather than displacements in classical submodeling sense.

Algorithm:

  1. Perform global analysis with coarse mesh
  2. Generate a submodel(a.k.a. initial submodel) analysis, with exact same geometry of global analysis with coarse mesh. This will allow one to get reaction forces where cut-boundary displacements are applied
  3. Extract reaction forces on cut-boundary faces
    1. Can extract reaction forces on whole surfaces and apply them as remote forces with deformable boundary option
    2. Can extract reaction forces on each node and apply in final submodel by ensuring same mesh on cut-boundaries between initial submodel and final submodel
  4. Generate a submodel (a.k.a. final submodel) with updated support design
  5. Apply reaction forces calculated from initial submodel
  6. Solve for final submodel and post-process

Example Case#1

I have built a simple model to test the above mentioned concept:

Set 1

 

 

 

 

Fig. Boundary conditions (a) Global model (b) Initial submodel

When I compare the stress at fixed support surface I get identical Von Mises stress distribution.

Set 2

 

 

 

 

Fig. Von Mises stress at fixed support surface (a) Global model (b) Initial submodel

An APDL code is developed to extract nodal reaction forces from the initial sub model as follows:

Can Image

The text file generated by APDL code based on “initial submodel”, is then manually copied to solver directory of the “final submodel”. This process can be automized by saving the file to “user files” directory instead.

The content of the reaction force text file is then read into “final submodel” by the following APDL code:

Can Image 2

Comparing the stresses and displacements there is perfect match between global, initial and final submodel models.

New Display Features

Two simple ease-of-use features have been introduced to improve graphics display for Mechanical applications in ANSYS R17.

“Color by Material”
While preparing material properties in Engineering Data, users can designate colors for materials. After assigning materials to geometry in Mechanical, change the “Display Style” (under Details of Geometry) to color by material.

This Mechanical R17 screenshot highlights tools to color by material and display by capped slice.

“Cap Sliced View”

The sliced view graphics display now includes the option to cap solid interiors with cross-hatches. The cap surface can be displayed by body color or entirely in red. Access the sliced view tool by clicking on the “New Section Plane” icon in the toolbar.

These new display feature help to better understand large assemblies and to export more-detailed images of geometry.

Please call Ozen Engineering Inc. and ask to speak with an engineer to learn how ANSYS tools can improve productivity and innovation in product development.


Tech Tip

Modelithics models are now compatible with ANSYS Electronics Desktop and HFSS circuit design. The Modelithics CLR Library for ANSYS HFSS improves the accuracy level of RF/Microwave electronic design. Once, the Modelithics CLR Library is installed into the ANSYS Electronics Desktop under the Component Libraries, designers can access the high accuracy simulation models by Modelithics from within the ANSYS HFSS design environment.

Modelithics CLR Library can be imported and solved with HFSS accurate EM co-simulation

The Modelithics CLR library contains Resistors, Inductors and Capacitors from the leading and popular vendors. The Modelithics models are measurement-based, scalable, statistical analysis capable and well-documented which make ANSYS HFSS EM simulation more accurate and valuable. The Modelithics models enhance ANSYS HFSS Electromagnetic (EM) co-simulation.

There are so many new features in R17 that we divided it up into three sessions and there is still not enough time to talk about all of the new features. The ANSYS marketing department came up with “ANSYS 17.0: Excellence Times Ten (10X)”. For an engineer like me, it really means 10X the productivity. What I have tested so far, all points to minimum 10X the productivity in R17. So, hold on to your seats, with R17, you will be more productive and happy with the application!

R17 is not the only news I would like to convey to  you; a couple weeks ago, Ozen Engineering, Inc. received a prestigious award from ANSYS, Inc.: “Channel Partner of the Year 2015”. When you go to our website and below, you will be able to see our picture taken with Jim Cashman (CEO of ANSYS) and Bob Kocis (VP of Sales ANSYS). We would like to thank you for contributing to our success in 2015. I would like to return the favor by making you successful in 2016! So, please feel free to reach out to me, metin@ozeninc.com, and let me know how I can help you with ANSYS products. Have a great February!

Tech Tip

Advanced ANSYS Workbench Files (MEMS Example)

kaan-80x80

Workbench provides an incredible amount of organization and automation for all your simulation files behind the scenes. Whether you want to be more appreciative of all that Workbench does in the background or you want to customize it for advanced applications, it helps to be familiar with what is happening with your files.

WB_Mech_files

The ANSYS Workbench file system for an ANSYS Mechanical project, including the temporary solution directory.

The typical Workbench project will have, at the top level directory, a <project name>.wbpj file and a <project name>_files directory, as shown in the picture above. Inside of this directory is where all the mysterious and automatic stuff happens. For a single ANSYS Mechanical system (Static Structural, Thermal, Modal/Harmonic, etc…) your directory of interest will be in the MECH directory, at the very bottom of the diagram. This directory can easily be opened in the ANSYS Mechanical application by right clicking on Solution in the tree and selecting Open Solver Files Directory.

Open_Solver_Files_Directory

Get to the important MECH directory quickly and easily by right clicking on Solution and selecting the highlighted option.

Inside the MECH directory is where all of the relevant files for the solution process are located. The mesh, loads and material properties are written to a text input file, ds.dat, and there may be several supporting files. The workflow here will be familiar to users of the old ANSYS Mechanical APDL interface (sometimes referred to as ANSYS Classic). This is where files needed for a solution process should be placed if they are not already handled by Workbench.

The actual solve does not happen here, however, it happens in the _ProjectScratch directory, located on the same top level project directory as the wbpj file. All the files in the MECH directory are moved here, the solve takes place and then the files are moved back. Workbench at this point will helpfully delete files that are unnecessary as per Analysis Settings (the MAPDL solver creates many files, see the documentation chapter File Management and Files under the MAPDL Basic Analysis Guide for a full listing). Note that any additional files that you may have manually placed in this directory are both automatically moved to the temporary solve directory and moved back. This also applies to new files created during the solution process, such as path results or images that are created by the /show command. So for a single analysis that needs non-standard support files, you can just drop your files in the MECH directory and they will available to the solver.

What if we need to deal with files that involve more than one analysis system? There are many ways in which two or more analysis systems could interact in a way that Workbench does not yet support. Examples include:

  • Updating a deformed geometry upstream (in R17 next week, this will be fully supported in Workbench)
  • Initial stresses or strains calculated in one analysis, written to an initial state file and applied to an upstream analysis through INISTATE
  • A common data file referenced by several analysis types
  • Any type of sequential coupled field analysis type

The user_files directory provides us with a common directory that we can use to store intermediate files. This allows us to avoid trying to predict the directory structure within Workbench or manually moving files each time it is solved. From the flowchart at the beginning of this post, this directory can easily be navigated to. It is also easy to find the path to the user files directory, along with other directories of interest, in APDL command snippets due to parameters automatically set in the solve process. See the beginning of the Solver Output file to find the following parameters:

_WB_PROJECTSCRATCH_DIR Absolute path to the temporary solution directory (Scr###)
_WB_SOLVERFILES_DIR Absolute path to the MECH directory
_WB_USERFILES_DIR Absolute path to the user_files directory for the project

We can construct paths using the APDL string or path manipulation commands and copy files between these directories easily. Here is an example of an APDL snippet that copies the result file to the user_files directory:

*dim,fname,STRING,128
fname(1)=strcat(_WB_USERFILES_DIR(1),'file')
/copy,file,rst,,fname(1),rst

For more information on the file operations commands available, see the File Management and Files section under the MAPDL Basic Analysis Guide. For more information on the string manipulation commands, see the very bottom of the Appendix B. GET Function Summary under the ANSYS Parametric Design Language Guide section in the documentation.

An example of the above input file is for a MEMS application. An electrostatic air gap is modeled and we are interested in measuring the capacitance as the gap deforms due to applied voltage. This could be a characterization for a Reduced Order Model (ROM), such as for the TRANS126 element. In Workbench, we can use the ACT MEMS extension set up both the deformed shape calculation and capacitance calculation in a Static Structural and Electric system, respectively. We can use the UPGEOM command to update the initial node positions of the electric analysis to the final deformed positions of the static structural analysis by referencing a result file in the user_files directory, copied there after the solve with the above command snippet. Because of our robust and automated setup, we can easily do a parametric analysis to automatically solve at several voltages:

Workbench System Layout, Deformation vs Capacitance/Voltage, solved deformation result of MEMS system.

Tech Tip

Antenna Integration on Platforms using HFSS

Electromagnetic Compatibility (EMC) is the ability of devices to work without any errors in their intended Electromagnetics (EM) environment and Electromagnetic Interference (EMI) is electromagnetic emissions from the devices that interfere with normal operation of other devices. ANSYS EM and Circuit simulation products provide fast and accurate EMC/EMI predictions— enabling Engineers to understand the EM interactions and system performance in early stage of product development. ANSYS tools needed for EMC/EMI Simulations are SIwave (Board Analysis), HFSS (Full 3D enclosure), and Designer (Realistic clock/timing, and digital signals). Full System EMC/EMI simulation methodology includes:ANSYS HFSS is a valuable tool in antenna design and platform integration that allow engineers to look beyond the antenna design and begin considering how it interacts with the system or platform into which it is integrated. HFSS Technology offers HFSS Finite Element Method (FEM), HFSS Integral-Equation (IE), HFSS Physical Optics (PO), and HFSS Transient. These antenna simulation methods and tools can be used depending upon the kind of problem you want to solve.

Antenna integration is a complex multi-scale and multi-domain problem. The major challenges in antenna integration modeling are accuracy, electrical size and scale, geometric complexity, platform materials, placement and co-site interference, and solution time. The antenna performance/characteristic can be affected after integrating on the platform (Far-Field pattern degraded, input impedance detuned…). Successful Integration of antenna systems on platforms requires that the design engineers overcome these challenge. Here are some tips and tricks to overcome the challenges:
  • De-feature models obtained from mechanical or electrical CAD tools when possible. (These models typically include geometry details insignificant for electromagnetic analysis)
  • Removing unnecessary model details reduces mesh density and runtime. (Use good engineering judgment to make certain that removed features are electrically insignificant)
  • Using ANSYS Electronics High Performance Computing (HPC) to reduce run time.
  • Using HFSS Hybrid Solution (Integral Equation, Physical Optics) or HFSS integration with SAVANT for large electrical size and scale.
