[CIG-SHORT] cohesive cells topology error

[Birendra jha]

Hello developers

Can you please help with the following error that shows up immediately after running pylith?

  File "/data/pylith/lib/python2.7/site-packages/pylith/topology/MeshGenerator.py", line 127, in _adjustTopology
    interface.adjustTopology(mesh, firstFaultVertex, firstLagrangeVertex, firstFaultCell)
  File "/data/pylith/lib/python2.7/site-packages/pylith/faults/faults.py", line 370, in adjustTopology
    def adjustTopology(self, *args): return _faults.FaultCohesive_adjustTopology(self, *args)
RuntimeError: Error occurred while adjusting topology to create cohesive cells for fault 'fault1'.
Error classifying cells during creation of cohesive cells.
  classifySize: 8, classifyTotal: 7

It's a 2D triangle grid with two faults in the grid and I only activate one of the two faults in the cfg file.

The grid quality is good (max condition number <2).

Many thanks
