Overview

User subroutine UPOREP:

  • allows for the specification of the initial pore pressure values of a porous medium;

  • can be used to define initial pore pressure values as functions of nodal coordinates and/or node numbers; and

  • will be called to define initial fluid pore pressure values at all nodes of a coupled pore fluid diffusion and stress analysis whenever user-defined initial pore pressure conditions are specified.
