The <problem> block

Parameters in this block are accessed by the problem-generator, and therefore depend on the problem being run. For example, the problem-generator athena1.0/src/prob/shkset.c (which is used for the Brio & Wu test problem) requires the following parameter values in the <problem> block:

The *l and *r parameter names are specific to the Brio & Wu shocktube problem. In general, the input file for other problems will have different variable names in the problem block.
