Description
A zero or negative area was calculated for the mesh cell shown. This indicates an invalid cell where the vertices effectively form a straight line rather than a valid polygon.
Suggestions
Review the mesh at the location shown in the GIS messages output file and regenerate the mesh to resolve the invalid cell.
If the mesh cell looks reasonable, is the model a longitude/latitude model? If it is, ensure that Spherical == 1 is specified.
