Today we welcome another guest post from Kyle Koppenhoefer of AltaSim Technologies, a COMSOL Certified Consultant. In this entry he will discuss modeling MEMS energy harvesting devices. 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 […]

This week we are happy to have Kyle Koppenhoefer of AltaSim Technologies as a guest blogger. As COMSOL Certified Consultants, AltaSim can share valuable insights into using the software — today on the topic of meshing wave problems. As part of our efforts to assist COMSOL users in performing high-quality analysis, we recently used our bi-monthly email to remind users to include twelve degrees of freedom per wavelength when meshing wave problems. This article builds on our previous advice. Wave-type […]

Many of the products that engineers design experience cyclic stresses during use that are below the material’s yield stress; unfortunately, these stresses can still be the primary reason for failure. Thus, engineers and designers must find ways of including the effects of cyclic stresses when designing products for long-term use.
