[CIG-SHORT] Issue with Normal Orientation

[Romain Jolivet]

Hello, 

I am having some more problems with the orientation of the vectors normal to the fault.

My problem is in 2D, with a fault slicing the entire medium (see tar ball attached).
The fault is FaultCohesiveKin class. I enforce the slip.

When I run with 1, 2, 3, 5, 7 or 9 nodes, I have one orientation for the vectors normal to the fault.
When I run with 4, 6 or 8 nodes, I have the opposite orientation.
I haven’t tried with more nodes.

That should not happen, right?

In terms of codes versions:
