GridBase<>::boundingBox().inbounds() does not work correctly with torus topologies

[klreuther]

If the grid overlaps the boundaries of the actual simulation domain, it should include cells on the other side of the domain. The bounding box does not reflect that.

Not Working:

Coord<3> c(x, y, z);
box = grid->boundingBox();
if (box.inbounds(c))
   { … }

Workaround:

Coord<3> c(x, y, z);
Coord<3> relativeCoord = c - box.origin;
Coord<3> normalizedRelativeCoord = 
	LibGeoDecomp::Topologies::Torus<3>::Topology::normalize(relativeCoord, gridDimensions());
if (box.inBounds(normalizedRelativeCoord + box.origin))
  { … }
