Free Webinar: Simulating Thermal Management in Structures

Engineers spend extensive time developing thermal management solutions for structures subjected to high or low temperatures. These challenges continue to grow as more complex structures and temperature distributions are required for nominal operations. In many cases, operational changes during the life of the structure have unintended and damaging consequences that require engineers to develop unique solutions to the damage that develops.


Standard heat transfer mechanisms like convection, conduction, and radiation need to be considered in determining the thermomechanical load on a structure. Accurate representation of convective heat transfer may require a fluid dynamics solution, and internal heat generation may be a primary heat source.

In this presentation, AltaSim’s Kyle Koppenhoefer will discuss the development of a model structure subjected to a complex thermal environment. The webinar will also include a live demo in the COMSOL Multiphysics® software and a Q&A session.

Computational Simulation for Medical Devices
Jeff Crompton and Kyle Koppenhoefer founded AltaSim Technologies 15 years ago to help elevate our customers’ technology through the use of advanced computational simulation. Over the last 15 years, we’ve had the opportunity to work with amazing companies from all over the world to develop simulations that impacted their technologies. Many of these companies have designed medical products based on our models, and these models have supported submissions to the FDA. We have successfully assisted our customers with medical technology development in minimally invasive cardiovascular devices, imaging technology, surgical instruments, biotechnology, drug delivery, tissue ablation and diagnostic bioassays as well as other critical areas.We believe there are more companies that could benefit from computational simulations, and we are actively looking to identify those companies that are based in our home state of Ohio.
Computational simulation is widely used in many industries and is increasingly becoming important in the development of medical devices and life science applications.  It can help provide insight into device performance, exploration of design space, examine treatment efficacy, refine ideas faster and more accurately, and reduce expensive prototyping and testing. The FDA recognizes the value of computational simulation and has now begun actively encouraging its use to support device evaluation, verification and validation.
In this 30 minute webinar, we will discuss the benefits of computational simulation for medical devices, and demonstrate its use for devices requiring fluid transport, structural stability, electromagnetic interactions and biological materials. An overview of applications to several medical devices and life science applications will be discussed and at the end of the webinar a Q&A session will be available.
Register for our FREE 30-minute webinar on Wednesday, June 7th at 10:00am.  Seats in this webinar are limited.

COMSOL Conference 2016 Follow Up

Each year we invest some of our time at the annual COMSOL Conference in Boston during the first week of October.  As usual, this investment provided us with the opportunity to grow our relationships with our friends at COMSOL and many of our clients. In addition, we were able to meet many people that were new to COMSOL and the Conference. Below are three specific highlights we wanted to share.


We were fortunate to be able to present some of the work we have conducted with Eric Dunlop of Pan Pacific Technologies in the Simulating Chemical Processes and Devices Session.  The session was chaired by Fulya Akpinar from Bristol-Myers Squibb, and she also presented a paper on her work relating to modeling of mixing in pharmaceutical drug batch reactors. This paper described the use of COMSOL to improve success in scaling up their reactors from the lab to plant. By using the rotating machinery capabilities within COMSOL, Akpinar’s group was able to account for the specific reactor geometry in their models. This model included the flow, reaction/transport of species and heat transfer. Using this Multiphysics model, they were able to predict the crystallization process for a batch reactor. Akpinar, et al. received a well-deserved best paper award for their work at the COMSOL Conference.


In addition, Bernard McGarvey from Eli Lilly and Company gave an excellent Keynote speech on how modeling can enable thinking about problems from first principals to improve their process and equipment design. AltaSim has had the pleasure of working with Lilly to help design new products, and they have made great progress through the use of computational modeling. Sebastien Perrier from Echologics Engineering also gave a superb keynote talk on how his company has been able to deploy a COMSOL-based simulation app to help non-engineers make decisions about the location of leaking pipes in municipal infrastructure applications. AltaSim believes that Simulation Apps represent an exciting opportunity for extending the benefits of computational simulations and has developed a series of Simulation Apps that will be available for general use shortly.


COMSOL also released a new version of COMSOL Multiphysics, Server and Client at the Conference. AltaSim has experienced significant challenges developing our larger models in earlier version, but with update 2 of v5.2a focusing on performance issues associated with large geometric models, we can see the improvement in rendering and meshing these models. If you have experienced these types of issues with large models, this new version will noticeably speed up performance.


If you were at the conference let us know what you discovered so that we can pass it on to the community.


Until next time…
