Issues with coupling
 

I am trying to couple two different cell types that do not line up along the mesh line. Below is an example of the errors I am getting. Is there any way to resolve this? Thank you in advance.

**ERROR - MASTER CELL 1049252 FACE 1 OF COUPLE 428589

IS A SLAVE IN COUPLE 425335

Re: Issues with coupling
 

In all couples you have a single "master" and several "slaves". Think of it as a left side and right side. Its arbitrary whether you match left to right or right to left. The error is that if a face is a master face in cpmatch, it must be the master in all cpmatches its in. If a face is on the left side for one, it must be on the left for all. Somehow in the way you are specifying cpmatches, you are not consistent in what is left and what is right.

This error can occur if the couples are not created in one step. And it is better instead of using cpcreate,cset (cset of cracks) to assign the master cells to on cell type (with the bigger cells and the slave cells to the other cell type.
