An incompressible magnetohydrodynamics solver

A two-dimensional nonlinear incompressible magneto-hydrodynamics (mhd) code is presented to solve steadystate or transient charged or neutral convection problems. the flows considered are incompressible and thedivergence conditions on the velocity and magnetic fields are handled by a relaxation scheme as pseudo-iterationsbetween the real time levels. the numerical method takes the advantage of a matrix distribution scheme that runs onstructured or unstructured triangular meshes. the time-dependent algorithm utilizes a semi-implicit dual timestepping technique with multistage runge-kutta algorithm. it is shown that the code developed here can beaccurately used for the solutions of incompressible navier stokes or mhd equations.
