How to Create a Randomized Geometry Using Model Methods
What does cheese have to do with setting up a COMSOL Multiphysics® model? Here, we use the random holes in a piece of Swiss cheese to demonstrate creating randomized geometries with methods.

Thermal Equilibrium and Nonequilibrium Heat Transfer in Porous Media
Heat transfer in porous media can occur under thermal equilibrium, such as a rock consisting of different minerals or trapped fluids, or nonequilibrium, like a thermal energy storage (TES) unit.

Estimating Pi Using the Monte Carlo Method and Particle Tracing
We take a popular way to estimate the value of pi, the Monte Carlo method, and add particle tracing simulation to the process for a fun way to visualize the results.
