[Users] 2D simulations (axial symmetry) with GRHydro

[Jens Mahlmann]

Dear all,

I am currently trying to set up an easy GRMHD simulation using axial 
symmetry. In the documentation I find the thorn Cartoon2D recommended 
for general axisymmetric problems. Is the use of Cartoon2D possible with 
evolutions in GRHydro? Doing my setup I do find a lot of NaNs in the 
Prim2Con routines.

Thank you and my best from Valencia
