hi Ian,
many thanks for the parameter file. this allowed me to go a little further (i was missing CoordBase::boundary_shiftout_z_lower = 1 and CoordBase::boundary_shiftout_z_upper = 1). however, i'm still getting the following error:
ERROR from host meurglysIII process 0 while executing schedule bin (none), routine (no thorn)::(no routine) in thorn Carpet, file ./Cactus/arrangements/Carpet/Carpet/src/SetupGH.cc:2512: -> There are not enough ghost zones for the desired spatial prolongation order on map 0, refinement level 0. With a spatial prolongation order of 5, you need at least 3 ghost zones.
i'm setting:
Carpet::prolongation_order_space = 5 Carpet::prolongation_order_time = 2
driver::ghost_size_x = 3 driver::ghost_size_y = 3 driver::ghost_size_z = 0
i'm guessing that in the example you provided things worked because you only had one grid? is there any way of doing this with more inner levels?
Hi,
I have never tried to do this with mesh refinement, no. This might be a limitation in Carpet, because perhaps it tries to prolongate with the same order in every direction.
