I have a material with a crack in it with applied K field at the boundaries. This is a nano-scale material and the mesh at the initial crack tip is very fine. Therefore in my current code i monitor either the level set front on cohesive zone opening to determine crack tip position and move the crack tip by using current solution and project it onto the original mesh. In this fashion the crack almost always stays at 0,0 while simulating crack motion.

I would like to accomplish this in oofem using primvariableMapper or equivalent. Presumably this is done in the engineering model. I would like some assistance in doing this.

Any help will be much appreciated.
