Dear collegues,
I am doing consolidation problem for saturated 1 m clay layer with 6 m sand layer above.
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.
I just keep getting the following error message:
The sum of initial pressue and elastic tensile strength for the porous elastic material in element 1 instance part-1 must be positive.
Would you advise what can I do to solve this issue.
