I will proceed step by step.
...
constitutive_dislo.f90 contains a modified version of Anxin's dislocation based model. As far as tested it, I consider it now error free. Mechanical twinning is NOT implemented YET.
mattex.mpie file is modified in accordance with the changes in constitutive_dislo.f90
It would be a great help if someone else can check the implementation. I may have overseen something.

SingleCrystallite now takes/stores Lp guess
CPFEM_Taylor (missing in GIA!!):
former fully plastic guess for Lp has been exchanged by keeping the last converged Lp (global array CPFEM_Lp) to serve as new best guess for the next time step. This speeds up the inner loop of TimeIntegration.
