In the field of laser generated high energy density physics, hydrodynamics is a very popular approach to describe the created plasma. In the present work, we treat the energy conservation equation of the radiationhydrodynamic model [1]. Particularly, we aim to simulate spatial-time evolution of a coupled system of plasma temperature and radiation field which is provoked by absorption of intense...

A parallel electrostatic Poisson’s equation solver coupled with parallel adaptive mesh refinement (PAMR) is developed in this paper. The three-dimensional Poisson’s equation is discretized using the Galerkin finite element method using a tetrahedral mesh. The resulting matrix equation is then solved through the parallel conjugate gradient method using the non-overlapping subdomain-by-subdomain ...

Adaptive numerical methods offer greater efficiency than traditional numerical methods by concentrating computational effort in regions of the problem domain where the solution is difficult to obtain. In this paper, we describe progress toward adding mesh refinement to MPSalsa, a computer program developed at Sandia National Laboratories to solve coupled three-dimensional fluid flow and detaile...
