WebSep 22, 2015 · 1 Answer Sorted by: 4 One way to do it might be to create an internal Line Loop in the input file where the crack originates. To do this, you would create 2 points at each end of the crack in your .geo file (say, points 1,2,3,4), and connect them up with lines. Then, create a Plane Surface from the border of that zero-thickness line loop. Simple, extensible python library to read a finite element mesh and insert cohesiveelements. Meshes are partitioned into sectors using METIS mesh partitioner, and cohesiveelements are inserted between partitions.
