Ozen Engineering Newsletter – May 2016
Message from your Channel Partner
By the time you read this message, R17.1 will be available for you to download from the customer portal. One of the most important new features in R17.1 is that Reaction Design Products (specifically Chemkin) are now included in the product installation. For ANSYS CFD users, this is an important product especially for inclusion of chemical reactions. In addition, SpaceClaim Direct Modeler is now available as a stand-alone package. If you have not used SpaceClaim for geometry creation yet, you may want to start allocating time to learn this amazing solid modeling tool, which will be the main solid modeling tool of ANSYS in the near future. Also, you may want to visit ANSYS YouTube page to take a look at an extensive library of How-To videos: https://www.youtube.com/user/ANSYSHowToVideos
May is a busy month; since many engineers/users will be taking vacation time off in June, we are trying to squeeze in training classes and Lunch & Learns (L&L) in May. Please sign up for Introduction to ANSYS Mechanical as well as ANSYS/Maxwell. Also, please sign up for our free Lunch&Learn sessions covering new “Nonlinear Structural Features” and “Multiphysics AIM”.
Please let me know how/if I can be of help with ANSYS software tools. Have a great May!

What’s New at Ozen Engineering?
Signal Integrity and Power Integrity Analysis Services
Ozen Engineering is pleased to introduce Board and Package Level Signal Integrity Analysis Services. These services add and complement our list of thermal and stress analysis services for boards and packages.
As the speeds of interfaces become faster, Signal Integrity for board traces and package traces is no longer an after-thought, but has become a “before thought”. Chip-Package-Board co design has not only to be done for optimizing the package and board layout for layer count reduction, but also to analyze and optimize the performance of chip to pkg to board channel. All this is now required before signing off on chip tape-out, package manufacturing, and board manufacturing.
Ozen Engineering has established an experienced team of Signal Integrity and Electrical modeling experts who can provide SI/PI services to the customer for optimizing on chip i/o pad layout, package design, and board layout.
Tech Tip
- 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
One 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 =
500You 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= 0.00000000Writing 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

0.025962 0.021216And of course there are all the plotting and visualization functionality that you are used to:
bar3(table2array(tab))
You can similarly interface with Workbench and Fluent with this toolbox.
We are pleased to make this ANSYS Matlab Toolbox available early for our customers (please log in):

Whitepaper
Dramatic Changes in Sports
For 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.
