hi Erik,

thanks for your reply. i've tried to set the parameters as you described, but i'm getting a Carpet 
assertion failure:

cactus_Lean_ET: Cactus/arrangements/Carpet/CarpetLib/src/gh.cc:61: gh::gh(const 
std::vector<vect<int, 3> >&, centering, int, centering, const std::vector<std::vector<bbox<int, 3> > 

&, const i2vect&): Assertion `all(box.shape() / box.stride() >= boundary_width[0] + 

boundary_width[1])' failed.

here's how i'm specifying my grid:

CoordBase::xmin                      = -48.00
CoordBase::ymin                      = -48.00
CoordBase::zmin                      =   0.00
CoordBase::xmax                      = +48.00
CoordBase::ymax                      = +48.00
CoordBase::zmax                      =  +0.00
CoordBase::dx                        =   2.00
CoordBase::dy                        =   2.00
CoordBase::dz                        =   2.00

driver::ghost_size_x                 = 3
driver::ghost_size_y                 = 3
driver::ghost_size_z                 = 0

CoordBase::boundary_size_x_lower     = 3
CoordBase::boundary_size_y_lower     = 3
CoordBase::boundary_size_z_lower     = 0
CoordBase::boundary_size_x_upper     = 0
CoordBase::boundary_size_y_upper     = 0
CoordBase::boundary_size_z_upper     = 0

CoordBase::boundary_shiftout_x_lower = 0
CoordBase::boundary_shiftout_y_lower = 0
CoordBase::boundary_shiftout_z_lower = 0

am i missing something?
