Progress on implementing general parallel moment equations in NIMROD

General parallel moment equations are implemented in NIMROD to obtain parallel closure relations for time-dependent fluid simulations. The parallel moment equations are obtained by taking velocity moments of the first order drift kinetic equation. By truncating the moment equations at a certain order of moment, a system of moment equations can be solved. The parallel closure relations are obtained from the moment solution. For less collisional plasmas, the convergence of parallel closures is shown by increasing the number of moments of the system. As a benchmark test, ion parallel flows and bootstrap currents are compared to continuum kinetic calculations in NIMROD.
