How to Export Plot Data in COMSOL Multiphysics

Post processing is the last of the five primary steps of simulation development. This step represents the payoff from all the hard work of the previous steps, and it drives the deeper understanding of the design that engineers obtain though simulation. A simulation engineer can significantly improve their understanding, and better communicate that understanding, when […]

Data Storage Options for Dynamic Simulations

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

Model Parameterization, Part Two: Ball, Box and Cylinder Selections

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.

Model Parameterization, Part One

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
