1 General description

The mhdFoam solver is currently an incompressible magnetohydrodynamic equation solver. It solves the coupled Maxwell-Navier-Stokes equations for an incompressible fluid. The fluid electrical conductivity is presumed constant.

The script to compute the analytic solution can be found here: http://code.google.com/p/mhdflow/source/browse/

Result: On a mesh of 120x66x66, and ensuring a fully developed flow, the following result is obtained. It can be seen that mhdFoam does not perfectly reproduce the reference solution.
