Fixed and non-fixed length q studies using a 1-D Lagrangian code on the variable zoned I-D hydro shock test problem
Technical Report

OSTI ID:5469671
A 1-D Lagrangian code that employs a von Neumann-Richtmyer staggered mesh difference scheme was used to investigate the roll of the artificial viscosity, q, in the errors associated with the variable zoned hydro shock problem. In particular, it was found that a fixed length q (i.e., a q which spreads shocks over a fixed physical length) would eliminate this error. Further, the errors associated with the standard use of q which spreads shocks over a fixed number of mesh points was investigated to possibly select a best form.
