Dear Jean-Paul, Thank you for the suggestions. I have already looked through the "Applications" and found that "PRISMS-Plasticity" is working on similar lines (Crystal Plasticity FEM). The nature of the problem is : Multi-scale simulations using Crystal Plasticity FEM.
Over the years we have developed the UMAT subroutine that describes our material models. So, instead of implementing them from scratch in dealii we would like to have an interface that communicates between the UMAT and dealii. So, my question is: Has anyone tried to link the UMAT subroutines with dealii ? i.e., The UMAT (fortran 90) has to be called at each integration point. If not, How do I go about linking the fortran code with dealii ? Thank you! Mahesh Prasad.
