,That negitive stain will not be an issue and Mohr coulomb is best as it is tailored for Geomechanical analysis, Have you implimented any of the resoultions i suggested in the first post?nCan you able to do Grid Independce test ( reduce the mesh size of the part and see if you see same negitive strains) if you see it , I would recommend to change the Formulation to SPH as it emmulates the rocks and suited for Brittle materials. comment down your outcomsnCheers, Ram n
