Crosswind diffusion

Crosswind stabilization (green line) does not only add diffusion in the cross direction, it also captures discontinuities and, therefore, removes the numerical under- and overshoots. Consistent stabilization methods (streamline together with crosswind stabilization) are usually more efficient, because … See more COMSOL Multiphysics uses the finite element method (FEM), which is a well-known and established approach to solving the governing Partial Differential Equations (PDEs) … See more To better understand the effect of stabilization methods, let’s look at an example and solve it with COMSOL Multiphysics. We … See more No need to change the default stabilization settings! Our developers, here at COMSOL, have done a fantastic job adding consistent … See more All transport interfaces, such as heat transfer, fluid flow, or species transport, automatically use stabilization.
