Map irregular Abaqus FE mesh to square grid

Matlab code to access results exported from Python. User will need to alter code to point to correct file path (line 5). Folder containing this and the other Matlab code needs to contain a subfolder called "Functions", which is to contain:

inQuad.m
intersectQ.m
Lintersect.m
orient3.m
shoelace.m

These five functions are for calculating the overlap between two shapes, as part of mapping an irregular mesh onto a square grid.
