As an engineer have you ever found yourself in a situation where you’re trying to track non-converged results by plotting solution variables that you would expect to behave in a certain way, but you’re not sure how to modify the initial values? In our latest Tips & Tricks video, I take you through a scenario …

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 …
Technology continues to evolve, making our lives a lot easier in many ways. And, when it comes to Multiphysics, the Least-Squares Fit function of COMSOL 6.1 is no exception. Before this function existed, engineers had to develop their own coding to perform this type of fitting. But, in our latest Tips & Tricks video, we …
We are excited about the new release of COMSOL Version 6.1 and wanted to share a new feature with you, so we put together this quick video. To help you follow along, we have included the video transcription below. If you’re new to COMSOL, we invite you to register for our introductory class, Multiphysics …
User-defined materials provide the flexibility needed to design models using a combination of existing material properties and properties defined by the user. These material properties can also be included in a user-developed material database for easy access to frequently used materials. Users often spend significant time developing models with material properties not available in the …
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 …

Many of the simulations we have developed through the years include materials that behave anisotropically. This class of materials has different material properties in different directions. This anisotropy often needs to be included in computational models to achieve the desired level of accuracy in the simulation outputs. If the material coordinate system of the anisotropic …
Thermal stresses are an important design concern for many engineering applications. When temperatures change, materials can deform or warp leading to the build-up of internal stresses even without the presence of external constraints which can further increase thermal stresses. Modeling and simulation can calculate the deformations, stresses and changing contact pressures using thermal-structural interaction techniques. …
