What is the role of Engineering Simulations in Internet of Thing (IoT) ?

/in /by

By 2020, there will be 26 smart devices for every human being on Earth according to one estimate.  IoT will result in an explosion of products with integrated antennas and sensors and world is more connected than ever in IoT age. However, IoT brings some Engineering challenges, most particularly the increase in complexity of the products and their operating environment. Engineering challenges for IoT are developing and managing Things, Network and Data/Cloud. Engineers must consider and include the comprehensive characteristic of environment in their designs. Well, engineering simulation is the golden key and ANSYS simulation technologies are speeding the development of three IoT elements: IoT devices, networking infrastructure and cloud computing platforms. Engineers need to create virtual prototypes and simulate them to make sure they will work in the real world. Common design challenges for IoT are Structural and Thermal Reliability, Power Management, Communication Efficiency, Privacy and Security, Multiple Standards, Quality of Service, Energy Efficiency, and Miniaturization. Design Engineers must overcome these challenges and no other technology can help engineers, more than engineering simulation. ANSYS offers a comprehensive solution for IoT industry challenges with simulation tools for electronics, semiconductors, embedded software, mechanical structures, fluids, and heat flow.

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))

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

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.

Internet of Things (IoT)

Engineering IoT with ANSYS

/in , , , , /by

MaryamNemaziePicWhat is the Internet of Things (IoT)? Our world is more connected than ever, thanks to the growing web of smart electronics that surround us every day. IoT is about enabling connectivity and embedded intelligence in devices. This connectivity will greatly streamline communications among our electronic devices, improving the way we live, work and play.

For Ozen Engineering, Inc. and ANSYS customers, creating innovative products with technologically demanding qualities is nothing new. The complete simulation and workflow technologies used to develop the ground-breaking products all around us are ready for the next generation of ubiquitous connectivity. Whether for stress, thermal, antenna, and power design applications, our simulation technologies are speeding the development of IoT devices, networking infrastructure, and cloud computing platforms.

Why are simulations so important in an IoT world?

IoT is here and it’s growing fast. Many companies don’t realize the power of conducting simulations, especially in the context of IoT. Generally speaking, ANSYS simulation technology allows innovators to develop higher quality products, reduce the cost of prototyping, and improve time to market. In essence, ANSYS simulation software allows you to predict with confidence that your products will thrive in the real world. In the context of IoT, simulations are now more important than ever because as all of these devices are connected, signal and power integrity become crucial. Innovators have to monitor the electromagnetic compatibility among all of these devices to ensure that the various signals are not interfering with one another.  What’s the point of embedding intelligence in devices if signals interfere, undermining the power of the device? However, electromagnetic interference is not the only issue to watch out for. There are a whole host of considerations, such as thermal and reliability issues, just to name a few! This is where ANSYS simulation software, such as an ANSYS Multiphysics package, unleashes the power to alleviate such concerns and would be just the tool in creating a reliable, high-performance prototype.

Find out how ANSYS simulation solutions can help you engineer high-performance electronic devices and systems for the Internet of Things by watching this brief video. Hungry to learn more? Please visit our ANSYS training schedule for upcoming courses: http://www.ozeninc.com/ansys-training-events/.  If you are interested in a technology demonstration, please contact Casey Heydari at 408-732-4665 or casey.heydari@ozeninc.com to schedule a demo today.
