What is FEATFLOW?
FeatFlow (Finite Element Analysis Toolbox for Flow) is a finite element CFD Fortran code using a very efficient FEM discretization together with a geometric multigrid approach for solving linear systems. This results in a very fast and computationally efficient solver, typically yielding a magnitude or more of speedup compared commercially available solvers. FeatFlow can be used from MATLAB with the FEATool Multiphysics GUI interface.
