Hi,
I am struggling with the interpretation of effective stresses. So far I used version 9.00 of FLAC3D. concept is: deplete a disk shaped reservoir at around 1800m depth.
I start applying the total stresses loading with gravity based on density and an initial total stress ratio.Then I use the example Input Instructions for Fluid-Flow Analysis — Itasca Software 9.0 documentation as a guide for applying delta pressures based on zone.pp. (apply 0 pressure two times when there is no depletion and applying a negative delta pressure at the reservoir zone)
I notice now that the total and effective stresses plotted along a vertical profile through the reservoir look different based on the version I use to open the *.sav file:
Has there been a change in plotting/interpretation of the effective stresses with this option? (I studied the release notes, but did not find anything related, maybe I do not catch it).
