[Users] [Einstein Toolkit] #2067: Tov collapse sim not working

[Mikael Sahrling]

Thanks Roland,

Interesting point. I can play with the initial setup a bit. 

Where is eos state change initiated? I believe the collapse occurs because there is a sudden lowering of the pressure !?

I'll poke around some ...
