Dear all


I see in the python documentation that  the mesh class has a function normal_of_face


I would like to compute the mean normal at node points (mean of the faces normal to which this point belong) on the exterior surface of the mesh

I have the list of those points id


This is to do a direction test for setting boundary conditions


Thank you
