# PROBLEM DEFINITION FILE: Sedov Blast (2D AMR version)
#
#  A 2D explosion test problem.
#
#  Since this is a 2D problem you may want to redefine
#  the maximum size of subgrids defined in ProtoSubgrid_AcceptableGrid.C
#  as "#define MAXIMUM_SIZE 2000" and recompile the code.
#  2000^(2/3) would be a better value. Also note that this restriction would
#  be in effect ONLY in multiprocessor runs.
