I try to import a hex mesh into fenics using the method as suggested in:
https://fenicsproject.discourse.group/t/transitioning-from-mesh-xml-to-mesh-xdmf-from-dolfin-convert-to-meshio/412/3?u=reinhardt
This did not work yet.
*** Error: Unable to order quadrilateral cell.
*** Reason: Cell is not orderable.
*** Where: This error was encountered inside QuadrilateralCell.cpp.
*** Process: 0
***
*** DOLFIN version: 2019.1.0
*** Git changeset: 74d7efe1e84d65e9433fd96c50f1d278fa3e3f3f
But if I pull the dolfinx docker and say “import dolfinx”, I still get the error message
ModuleNotFoundError: No module named 'dolfinx'
What would currently be the best way to work with a hex mesh?
