Tips & Tricks

At AltaSim, we take time to evaluate each new release of COMSOL Multiphysics. The changes that COMSOL implements can have a significant impact on how to use the software. Having a deep understanding of these changes helps us serve our clients better. We also pass on our insights via Tips & Tricks so you can benefit […]

At AltaSim, we await COMSOL’s improvements to their software with great anticipation.  We take time to evaluate these changes to determine what we can use to better serve our clients.  Based on our review, we also pass on our insights via Tips & Tricks. Version 5.6 of COMSOL Multiphysics has introduced serval solver improvements that

Many simulations are quasi-static, or steady state, because the results are independent of time.  Time dependent simulations introduce additional challenges over time independent cases.  The data generated during a time dependent simulation could be many gigabytes.  Thus, the simulation engineer needs to balance the volume of output data with their needs for data at critical

In last month’s Tips and Tricks article AltaSim introduced the topic of model parametrization, describing the process and a few of the benefits.  Effective parametrization of a model file takes time and thought to implement correctly.  This article will extend the approach discussed in Part 1 to include one important recommendation for robust geometric parametrization. 

When learning to use a simulation software such as COMSOL Multiphysics, users typically focus on learning the fundamental tools and steps for building a model and getting results, e.g. geometry building, applying boundary conditions, defining material properties, meshing and post-processing.  These skills are crucial for developing a working and useful model, so it is a great place to start. Once a user has acquired these basic skills for getting a working model, AltaSim
