Geostatic procedure for partially saturated soil
Dear collegues,
I do geostatic procedure for partially saturated soil.
ABAQUS is used.
The model of soil - Cam-Clay.
Initial stresses in the soil are given.
The initial pore pressure as well set.
Material data is fully specified.
Nevertheless - the program displays an error message:
The sum of initial pressue and elastic tensile strength for the porous elastic material in element 1 instance full-1 must be positive.
May be somybody knows the reason of the message?
