(OP)
Dear all,

I am actually engaged in the decision of geological problems. So we have a some model with the soil disk, there is a circular hole in the centre, witch has initial pressure at the first time(a modelling of the soil injection with the polymer solution). How can I recalculate by the subroutine DLOAD a normal pressure inside of the circular hole in the soil model if a nearest FEs were failed. Failure criteria is given by Mohr Coulomb criterion (https://en.wikipedia.org/wiki/Mohr%E2%80%93Coulomb...).

This is predictable behaviour : http://files.engineering.com/getfile.aspx?folder=7...
