Background:

Here, we'll test ProjectX on a three-dimensional hemisphere in compressible, inviscid flow (running in serial).

The solution, here, is not restarted. That is, the input file is a grid consisting of ### elements. A ###-order solution is then computed...

For more information, please consult the .job and .hist files located in the corner of each panel.

What is being tested?

Listed below are the tolerances for the relevant data compared in the history files:
