[FLASH-USERS] Unsupported boundary condititions

[Josef Stöckl]

Hi Anshu,

Yes, I'm indeed using the Multigrid solver. I didn't find any mention of 
this solver not working with "outflow", but I'll have to check again. I 
wonder though, isn't "grav_boundary_type" the boundary condition used 
for the self gravity? Because I had set that to "periodic" for my 
initial tests.

Thanks and best regards,
Josef
