[Users] Illegal number of boundary points

[Babiuc-Hamilton, Maria]

Hello,

It seems that CarpetReduce does not allow me to run the executable with the following parameter choice:

CoordBase::boundary_size_x_upper     = 0
CoordBase::boundary_size_y_upper     = 0
CoordBase::boundary_size_z_upper     = 0

CoordBase::boundary_shiftout_x_upper = 0
CoordBase::boundary_shiftout_y_upper = 0
CoordBase::boundary_shiftout_z_upper = 0

The offending line was commented out on Mac I I have forgotten about it.
Is there a reason I am overlooking of why I cannot have this combination of paramentes?

thank you,
Maria

Maria

The respective check (in line 96) ensures that the number of boundary
points is non-negative, and that it is not larger than the total
number of points on this process. Zero boundary points satisfy both
properties.

Can you check that this condition reads indeed

        if (bnd_points[2*d+f] < 0 || bnd_points[2*d+f] > cctk_lsh[d]) {

on both computers? If so, something is strange on the Ubuntu system.
