[FLASH-USERS] Unsupported boundary condititions

[John ZuHone]

Josef,

Following up on Anshu's recommendation, if you are using the multigrid  
solver the boundary condition you probably want to use is  
"isolated" (I'm guessing at what kind of problem you're trying to run,  
if you could specify that information that would also be helpful).  
This is what you need to set the "grav_boundary_type" parameter to in  
your flash.par. Other parameters, "xl_boundary", "xr_boundary", etc,  
should be set to outflow.

Best,

John
