Hello everyone

I am wondering how to insert the cohesive element between every two solid elements in Abaqus, such that each element can separate with others? Is there a tool can do this and generate Abaqus input file?

Thanks

Hi everyone

I am working on vumat subroutine for abaqus explicit. I know in the umat, the subroutine is called for each integration points. There are an argument that stand for integration number. So, I can output information (such as deformation gradient, stress ...) for each integration point.

However, in vumat, there's no arguments for integration points. I can only output element numbers. My question is, for an element with four integration points, how can I output information for each integration point? How the vumat is called for each integration point? Thank you!
