Hello! This code snippet ----------------------------------------------------------------------- from dolfin import *
m = Mesh() editor = MeshEditor() editor.open(m, 2, 2) editor.init_vertices(3) editor.add_vertex(0, Point(.0, .0)) editor.add_vertex(1, Point(1., .0)) editor.add_vertex(2, Point(0., 1.)) editor.init_cells(1) editor.add_cell(0, 0, 1, 2) editor.close() print MeshQuality.radius_ratio_min_max(m) ----------------------------------------------------------------------- gives this error (when Dolfin is built with MPI support) benjamik@benjamik-hp:~/tmp/dolfin$ python test.py *** The MPI_Allreduce() function was called before MPI_INIT was invoked. *** This is disallowed by the MPI standard. *** Your MPI job will now abort. [benjamik-hp:28604] Local abort before MPI_INIT completed successfully; not able to aggregate error messages, and not able to guarantee that all other processes were killed! The reason is that MeshQuality::radius_ratio_min_max() calls MPI::min() which calls MPI_Allreduce(). Who is responsible for initializing MPI in this case?
