June 2015 OEI Newsletter

Message from the President 

Summer is here! Officially, summer will be here on June 21 at 9:38AM local time. As we are thinking about summer vacations and family time, we are also entering one of the busiest work periods here at our company. Two weeks in a row, we are having Introduction to ANSYS Mechanical class, sold out in both cases. We have rescheduled our training  program to add additional ANSYS Mechanical classes to accommodate the increased demand. This is actually in accordance with the increased interest and sales of our ANSYS software tools. Feel free to contact me if I can be of help with your FEA & CFD software needs. Have a great summer!

Simulation Technology is Revolutionizing the Healthcare Industry

“Four best practices to ensure smooth technology shift to computer modeling and simulation for medical device and pharmaceutical organizations”


Healthcare is changing rapidly. Recent advances in technology are completely revolutionizing how we approach the prevention, diagnosis and treatment of illness. And this is just the beginning of what will be a technological revolution in healthcare. Simulation is playing a major role in pushing the envelope of this technological breakthroughs.

Smartphone use is growing at an enormous pace. They now account for 87% of the total mobile handsets in the US, for example. And with the smartphones has come hundreds of new apps related to health and fitness. These apps do everything from monitoring sleep and movement (steps), to keeping track of glucose levels, blood oxygen, and even ovulation.
The relentless rise of wearable connected devices is also having a big effect on people tracking their health and fitness. These small devices are light and easy to wear, and they communicate with apps on the smartphone to monitor and record health-related information.

The next evolution of wearables, where they are built-in to the clothes you wear, has already begun. If these devices become as ubiquitous as smartphones, they will help us make far better informed decisions about our health and fitness.

Thierry Marchal, Director of Healthcare Industry at ANSYS recently published an editorial called “Entering the In Silico Era”. He mentioned:

“To provide safe, reliable and cost effective medical solutions, consumers and medical field alike are turning to treatments that are personalized, participative, predictive and preventive, called P4 medicine.

However, the P4 medicine won’t be possible without huge sets of data and the ability to continually monitor key parameters for each patient. To compile, manage and interpret such big data, researchers need computer models and simulation (CM&S) that describe healthy and diseased states in humans, which is also known as in silico medicine. This groundbreaking technology properly captures the vital conditions within and surrounding the implantables or wearable devices, including their sensors and monitors; shares data with other devices, doctors and patients; and suggests action plans that will bring the patient’s body back to a more healthy state.

Combining fluid, structure and electrical physics that drive the human body – a body that now interacts more than ever with connected devices that constitute the medical IoT – calls for advanced solutions in the healthcare field. At ANSYS, researchers progressively create and develop technologies to provide the medical and pharmaceutical worlds with a platform that allows development of a virtual physiological human (VPH).”

I invite you to read this exciting article about the four best practices to ensure smooth technology shift to computer modeling and simulation for medical devices.

 CAE-based robustness evaluation in virtual prototyping

 Luxury or Necessity?

Today, one of the greatest challenges is the rising number of numerical simulations of large tests and analysis including CAE-based optimization and CAE-based robustness evaluation while reducing the number of hardware tests. Also, the increasing usage of structural optimization may require CAE-based robustness analysis of “optimized” designs. In many cases, the optimization of cost, performance and weight lead to highly sensitive designs which can lead to substantial robustness defects especially in nonlinear systems. It is no suprise that the increase of virtual prototyping in conjunction with the reduction of hardware tests and development times combined with a very high innovation speed of new materials or electronic components do have some risk. This can be seen in the statistics of product recalls, which have increased significantly in the last few years. Therefore, the topic of CAE-based robustness evaluation assuring the serviceability, safety and reliability should be taken into account in virtual prototyping as early as possible.

SAR Measurement in ANSYS HFSS

By Mehrnoosh Khabiri


The wireless devices industries must comply with Specific Absorption Rate (SAR) regulations to bring their devices to the market. SAR is a measure of how the electromagnetic field is absorbed by the human body tissue. The SAR measurement makes it possible to evaluate if a wireless device satisfies the safety limits. ANSYS offers a solution to model SAR for the wireless devices, particularly biomedical/Health devices. ANSYS HFSS (high-frequency structural simulator) can solve the complex human body structure when an implantable/wearable device is placed in/on the body. Incorporating ANSYS Optimetrics and HPC features, many iterations can be performed in an efficient manner to investigate the SAR distribution.

Path & Surface Plots

By Kaan Divringi


Want to visualize your results outside the bounds of just your mesh elements? Construction Geometry allows you to do Path or Surface plots on arbitrary locations, interpolating results from the nearest node. Path plots can be defined between points, on edges, from edge results, or along the X axis of a coordinate system. You can also convert any result scoped to an edge to a path plot by the right click menu. For surface plots you can scope to an arbitrary plane and even sum up the force reactions through a chosen plane. Add the Construction Geometry node to the tree by Right clicking the Model object and clicking Construction Geometry in the toolbar.

June Training – Introduction to ANSYS FLUENT

Introduction to ANSYS FLUENT: June 22nd, 2015


The complete Intro to ANSYS FLUENT training is a 5- day training course. On day 1 the training will focus on geometry creation and specifically focus on ANSYS DesignModeler. If you know that you will be using ANSYS DesignModeler, then you should definitely plan on attending day 1 of training. Even if you don’t plan on using ANSYS DesignModeler, this day of training could still be helpful since we will discuss some things to think about when creating geometries for CFD analyses and we will also talk about the geometry cleanup tools in ANSYS DesignModeler. If you are unsure if the ANSYS DesignModeler training is right for you, please contact info@ozeninc.com


On day 2 the training will focus on creating your CFD meshes using ANSYS Meshing. If you will be using another program to create your CFD meshes, you may still find this day of training to be helpful because we will talk about some of the important things that you need to consider when creating CFD meshes. If you are unsure if the ANSYS Meshing training is right for you, please contact info@ozeninc.com.


On day 3 and 4 the training will focus on the FLUENT solver and how to setup, solve and post-process your results from ANSYS FLUENT.


Day 5 of the training is optional but strongly recommended for all commercial users of ANSYS FLUENT. This day is a great wrap-up to the week long training and provides the students with the opportunity to start working on their first FLUENT analysis with guidance from the instructor or instructors involved in the training.
