COMSOL Tips & Tricks – Text-Based Search Filter Many of us are running Multiphysics analyses with COMSOL. And, of course, the more physics we are solving for the more variables we have available for post-processing. Maybe you are like me and have gotten lost in the sea of available variables when clicking on the […]

Thermal Mitigation – Common Approaches If the operating temperatures remain outside the prescribed thermal budget established for safe device and component operation we are now faced with two options: either reduce the power levels that may change device functionality or increase the dissipation of heat to reduce the standard operating temperatures. In some

AltaSim has much to be Thankful for. As we approach Thanksgiving, all of us at AltaSim decided to share one or two technologies we are thankful for. Here’s our list: Jeff – I am thankful for the Turkey Deep Fryer… and for Fire Extinguishers! (And I’m glad I don’t have to eat Pumpkin

Can SpaceClaim Provide Frustration Management? In all our years of doing analysis, we have discovered that waiting can be frustrating. Broken CAD. Dirty Geometry. Simulation Delays. Mounting Frustration. We have experienced all four. And this causes a significant breakdown in the entire development cycle. And when we consider all of the other people we

So far we have explored preliminary ways to predict the temperatures in a circuit using simple thermal resistance network calculations. This post addresses improved thermal analysis for electronics cooling. Consistent exposure to high operating temperatures can lead to degradation of material properties and development of thermal stresses that can ultimately lead to device failure. The

Create The Future Design Contest Winners Congratulations to all the winners from this year’s Create the Future Design Contest. COMSOL and Tech Briefs Media Group again sponsored, along with SAE International. This was the 11th year the competition has been held. 925 entries from 56 countries made judging this year’s competition very difficult.

154,000,000,000,000 Reasons Back in July, we posted a Blog announcing Third Frontier Commission Invests in Ohio Businesses. Just recently, Douglas J. Guth in HiVelocity Magazine highlighted 154 Trillion reasons why. His article is a must read, especially for those Ohio businesses who have felt like they were part of the “missing middle.”

During our recent webinar with COMSOL on thermal-structure interaction modeling, we at AltaSim Technologies demonstrated modeling of a MEMS energy harvester that scavenges waste heat. Examples of sources for waste heat range from microprocessor chips, to internal combustion engines, to chemical processing plants. If the waste heat generated from these cases could be used to

Previously we have discussed ways to complete a feasibility thermal management analysis. For a given thermal budget, we want to determine whether the junction temperature will meet specifications for reliability and thermal runaway. In electronic systems that rely on air flow for cooling, convection is of paramount importance. Power dissipation due to convection
