I have experienced some strange behavior with the IntersectionDetector. When I carry out the cell searching as the first thing after the mesh variable has been created, the searching is successful. However, if I solve a pde and use the eval function, or a locally created intersection detector, some points are simply not found. Has anyone else experienced this (using the python wrappings) ?
