VOIDRI

User subroutine to define initial void ratios.

User subroutine VOIDRI:

  • will be called to define initial void ratio values at material calculation points of continuum elements (see About the element library) in a porous medium whenever a user-defined initial condition on void ratio is specified; and

  • can be used to define initial void ratio values as functions of material point coordinates and/or element numbers.
