How to Compute the Projected Area of a CAD File in COMSOL®

January 20, 2022

Learn about three approaches to computing the projected area of a CAD file and when to use each one.

How to Run COMSOL Multiphysics® from the Command Line

December 9, 2020

Did you know that you can run repeated variations of the same COMSOL Multiphysics® model file from the command line — and automatically export data?

Strategies to Counter Small Automatic Time Steps

March 16, 2020

When solving a model, you may encounter a varying time step and discretization order, or NLfail or Tfail could be greater than 0. Use these strategies to improve the efficiency of the simulation.

How to Perform a Sensitivity Analysis in COMSOL Multiphysics®

February 6, 2020

How do the parameters of your design affect its performance? Understanding this relationship is a valuable part of the design process. By performing a sensitivity analysis, you can do just that.

Which Study Type Should I Use for My Electrothermal Analysis?

January 13, 2020

What’s the best interface to use when implementing electrothermal analyses in COMSOL Multiphysics? We go over the interfaces, study types, and multiphysics couplings for high and low frequencies.

How to Use Solver Suggestions in Acoustics Modeling

August 30, 2019

When you model large, industry-scale acoustics, ever find it challenging to efficiently solve the problem with the hardware at hand? Enter the solver suggestions in COMSOL Multiphysics®.

Automatic Time Step and Order Selection in Time-Dependent Problems

June 20, 2019

Here’s an intro to the time-dependent solver log in COMSOL Multiphysics® and an in-depth look at the theory behind discrete time-stepping schemes and optimal time steps and discretization orders.
