Boundary Sampling always overflows max points per grid cell

[mmdanziger]

Hi,

After compiling with the MakeFile I encounter:

./PDSample Boundary 0.02 /tmp/boundary.out
Internal error, point outside grid was generated, ignoring.
Internal error, point outside grid was generated, ignoring.
Internal error, point outside grid was generated, ignoring.
Internal error, point outside grid was generated, ignoring.
Internal error, point outside grid was generated, ignoring.
Internal error, point outside grid was generated, ignoring.
Internal error, point outside grid was generated, ignoring.
Internal error, overflowed max points per grid cell. Exiting.

This holds for almost all values of r that I try. What is going on? Is there some trick that I'm missing here?
