PVS-GRMHD: Conservative GRMHD Primitive Variable Solvers

[c]PVS-GRMHD: Conservative GRMHD Primitive Variable Solvers[/c][/b]
Abstract: Conservative numerical schemes for general relativistic magnetohydrodynamics (GRMHD) require a method for transforming between "conserved'' variables such as momentum and energy density and "primitive" variables such as rest-mass density, internal energy, and components of the four-velocity. The forward transformation (primitive to conserved) has a closed-form solution, but the inverse transformation (conserved to primitive) requires the solution of a set of five nonlinear equations. This code performs the inversion.
