Pretty sure BRL-CAD is only for solid modeling. This is the first I've heard that BRL-CAD can sim propellant combustion. Can you provide a pointer to documentation? I tried a few searches and couldn't find anything relevant. I've been meaning to learn BRL-CAD, but haven't had a strong motivator. This would be sufficient.
