Hello

we are experiencing some problems with the built-in cohesive elements, such as scatter on grain (part) boundaries, where several grains (parts) meet (material model was linear elastic, no orientations, so that shouldn't have happened).

i'd like to know if anyone knows of an alternative formulation for those elements (prefferably with a full tensor active, as opposed to only S33, S13 and S23, but it's not mandatory), either linear or quadratic.
I am already aware of some quad coh elements made by some Danes, but i'd like another example if there is one.
