Introduction to Numerical Integration and Gauss Points
In this comprehensive blog post, we go over the theory behind numerical integration, Gaussian quadrature, Gauss points, weak contributions, and much more.
FEM vs. FVM
Finite element methods, finite volume methods, or a hybrid approach: Which is the best choice for CFD? It depends on the fluid flow problem you’re trying to solve.
Course: Defining Multiphysics Models
There are 3 approaches to setting up a multiphysics model in the COMSOL® software: Fully automatic, manual with predefined couplings, and manual with user-defined couplings. Here, we discuss #1.
