Check the ordering of vertices #8

Closed alcarney closed 7 years ago

alcarney commented 7 years ago

It looks like that when we construct the global system from each triangular element we start from the vertex on the right angle and carry on counter clockwise. However the vertices we get in the .obj files from Blender start on some other vertex. Does this matter?

If so look at cyclically permuting the parsed faces we get back from the parser

Order does matter, a fix is implemented on the fem branch.

A "fix of the fix" is now implemented on the master branch - we now need to look a generalising it other boundary conditions
