Salome To OpenFoam worked well earlier. But for Salome 9.2 it is showing error upon execution.

The reason for the low performance I think is the use of a dictionary to look up which faces we traversed. As we loop over all cells we add them to either one of the lists owner or neighbour. And we need to know if the current cell is an owner or a neigbour. The current solution is to have a dictionary where the keys are the points of the face, e.g. "(1 3 4 51)". Dictionary lookups are quite fast but in this case way to slow.

Another way to accomplish the same thing would be to have a lboolean ist, traversedPoints. It would have the same length as the number of points, all elements would initially be false. Now when add a face we would set traversedPoints to True for all points belonging to that face. We know a cell is a neighbor to a face when all points of that face are true in traversedPoints.
