Third Frontier Commission Invests in Ohio Businesses Imagine attaching a “booster” to your business, and then imagine the possibilities for growth and expansion. Well, that’s just what the Ohio Third Frontier Commission recently did for Ohio businesses. We believe the following statement pulled from the linked article really says it all: “Many large manufacturers

We have just completed another successful COMSOL training class, Solving COMSOL Multiphysics Problems. How do we know it was a success? Because our attendees told us without us asking. Each of the students took time to share with us their thoughts on the quality of the course material and instruction. We are grateful for their

Many industries face increased thermal challenges with their electronic products. Customers often want devices with smaller form factors and higher functionality, but these changes create higher thermal fluxes and power density, which in turn require better thermal management to prevent device failure. From the electrical designer’s standpoint, getting traction on thermal problems may be

Wave propagation problems require sufficient mesh refinement to ensure twelve degrees of freedom per wavelength. This requirement develops from the error associated with approximating a sine wave with a polynomial. AltaSim Technologies shares this type of information regularly with users of the COMSOL Multiphysics software through our Tips and Tricks. If you are interested in

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,

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
