I'm trying to model large deformation problems in ADINA with frequent re-meshing. After each re-meshing, the filed variables such as stress and pore pressure will be mapped from the old mesh to the new mesh. For the next new step, the initial value of those filed variables should be specified same as the above mapped value. The ADINA manual only says how to define initial stress. But there's no clue of the initial value of pore pressure. Does anybody know that?
