MEMS Energy Harvester for Reusing Waste Heat

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 …

Mesh Refinement for Wave Problems

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 …
