Accessing External Material Models for Structural Mechanics
In COMSOL Multiphysics®, you can access not only material models derived from external libraries but also material functions programmed by yourself. We demonstrate with concrete damage model.
Does the Current Flow Backwards Inside a Battery?
What happens inside a battery? Does the current flow from negative to positive electric potential? Here, we explain the potential profile inside a battery during discharge and recharge.
Different Ways to Count Particles in COMSOL Multiphysics
There are 3 ways you can count particles in your particle tracing simulations in COMSOL Multiphysics: during postprocessing, using accumulators, or with the Particle Counter feature.
Exploiting Periodicity in Models with High Péclet Numbers
In the study of chemical species transport, a high Péclet number means the ratio of advection to diffusion is very high. Learn how to exploit periodicity when modeling this type of problem.
How to Solve for the Brachistochrone Curve Between Points
See how to use built-in mathematical expressions, the Optimization Module, and COMSOL Multiphysics® to solve for the brachistochrone curve.
How to Calculate Mass Conservation and Energy Balance
