Introduction Engineers, product designers and researchers often find our website and then reach out to us with questions about how AltaSim Technologies could be a guide on their path to solving challenges using COMSOL Multiphysics simulation software. I thought I would share some of the key components of these conversations to help you understand how […]
Radio Frequency Identification (RFID) technology has been around for more than 50 years and continues to evolve. Today, the technology uses electromagnetic fields to automatically identify, and track tags attached to both inanimate objects and living creatures. The great appeal of RFID technology is that unlike bar codes, it allows information to be stored and

In Part 1, we provided a basic introduction to Piezoelectric materials. In this blog, we will take a look at specific products that present a challenge for design engineers due to the need for increased output within smaller devices. Mics and Speakers Piezoelectric materials are used extensively in acoustics. Microphones contain piezoelectric crystals that convert
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

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
