As part of our efforts to assist COMSOL users in performing high-quality analysis, we recently used our bi-monthly email to provide a COMSOL Tips and Tricks update. In this tip, we remind users to include twelve degrees of freedom per wavelength when meshing wave problems. The following video demonstrates why twelve degrees of freedom per […]

This presentation provides an overview of quenching analyses as a specific example of conjugate heat transfer analysis. The presentation was given as part of a webinar on heat transfer analysis using COMSOL Multiphysics. Work conducted on analyzing air and oil quenching appears in this presentation. These quenching analyses include heat transfer mechanisms of conduction, convection,

Heat Transfer … … using COMSOL Multiphysics to simulate quenching of hot metal into an oil bath. This video shows how to set up partial differential equations as boundary conditions to describe the film boiling process. PDE boundary conditions within COMSOL Multiphysics provide significant flexibility for the user to develop complex models without writing separate

Thermal Management: A growing concern The demand for compact, multi-functional, high performance electronics has led to a dramatic increase in the power density of devices. In particular, the thermal dissipation per area of chip and per volume of system enclosure has increased dramatically in the last decade. To make matters worse, system-level requirements for small

Radiofrequency ablation (RFA) of non-resectable tumors has been shown to be as effective as surgical resection. During an RFA procedure, the tumor is heated to a temperature sufficient to cause cell death; the RF current is used to heat the tissue and there is no clinically significant electrical interaction within the tissue. While the

We held another Solving COMSOL Multiphysics class last week. Nine participants pursuing engineering excellence worked through the four-day course, and left Friday equipped to apply and interact with all the key features of COMSOL Multiphysics® Software. They learned how to use the software to build geometry, apply their physics, develop approximate meshes, use solvers and

One of the practices we believe in here at AltaSim Technologies is continued education. Thanks to some good people at Thomas Worthington High School in Worthington, Ohio, we had a chance to go back to school repeatedly over the last 2 years. Well, actually “school” showed up at our door when several students contacted us

In our “Breaking Traditions” entry, we mentioned the real life introduction to SpaceClaim that we received from COMSOL during the 2011 COMSOL Conference. Our solid model building has consumed less of our time and allowed us to focus on better analyses ever since. As is our commitment to our customers and the entire industry, when

Reviewing our work and looking at our other posts, it is easy to wonder if we ever talk about anything other than COMSOL or SpaceClaim or Tech Briefs or Multiphysics, etc? Our response… “What else is there?” (Just kidding.) Well actually, there is something else… People! Behind all these tools and talents and breakthrough discoveries
