We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

The INITIAL_STRESS_DEPTH sets the initial stress due to gravity, LOAD_BODY maintains that stress throughout the simulation

A zero initial effective stress is inconsistent with hydrostatic pore pressures

The pore pressures are available as a history variables in d3plot and elout - see the section on "Output" in the Remarks under CONTROL_PORE_FLUID

Unfortunately, I am not able to provide more detailed help in this forum, hopefully other community members can help
