mshr fails on simple off file

4 weeks ago by

I am trying to create a very simple mesh based on .off format exported from FREECAD with the following code:

from dolfin import *
from mshr import *

domain = Surface3D("")
mesh = generate_mesh(domain,2)

plot(mesh, interactive=True) only holds a circle.

This leads to  the following output:
Generating mesh with CGAL 3D mesh generator
[0]PETSC ERROR: ------------------------------------------------------------------------
[0]PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range
[0]PETSC ERROR: Try option -start_in_debugger or -on_error_attach_debugger
[0]PETSC ERROR: or see
[0]PETSC ERROR: or try on GNU/linux and Apple Mac OS X to find memory corruption errors
[0]PETSC ERROR: configure using --with-debugging=yes, recompile, link, and run
[0]PETSC ERROR: to get more information on the crash.
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 59.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

What the issue here? Do I something wrong? Or is this a bug in fenics.

Does anybody have the sample problem?

Thanks, Markus
