Poisson's Equation for a Point Source
This model solves the Poisson equation on a unit disk with a point source in the origin. The easiest way to describe a point source in COMSOL Multiphysics is by using an extra weak term.
To obtain the weak formulation of the general Poisson equation, we multiply it with a test function u_test an...

The Two-Term Boltzmann Equation
This model solves the two-term Boltzmann equation for an oxygen plasma. The solution gives the electron energy distribution function (EEDF) which then allows for self-consistent calculation of inelastic collision rate coefficients and electron transport properties. The equation is nonlocal in energy...

The Shallow Water Equations
The Shallow Water equations are frequently used for modeling both oceanographic and atmospheric fluid flow. Models of such systems lead to the prediction of areas eventually affected by pollution, coast erosion and polar ice-cap melting.
Comprehensive modeling of such phenomena using physical des...
