[FLASH-USERS] question about multigrid

[Sylvain Turcotte]

Hi all,

I am trying to run a model using the multigrid gravity solver in 2-D cartesian in flash4.4 and the run stops at the start with the following message:  "only one block allowed on coarsest level".
I have tried playing around with the set-up but I have not found why this is happening.

Any input is welcome.
Sylvain
