Question #665564 on Yade changed: https://answers.launchpad.net/yade/+question/665564 Jérôme Duriez proposed the following answer: This being said, it is nevertheless possible for you to back-calculate this excess pore water pressure "u" considering that - triax.meanStress corresponds here to the mean effective stress p' from actual experiments - that u = p - p' where p is the mean total stress that would be measured during experiments - and accounting for the q-p relation pertaining to triaxial tests, where q is the deviatoric total stress = q' the deviatoric effective stress which you can directly measure in your model.

Question #665564 on Yade changed: https://answers.launchpad.net/yade/+question/665564 Status: Needs information => Answered Jérôme Duriez proposed the following answer: Hi, At the moment, there is nothing in your script (e.g. in your O.engines list) that would simulate the presence of pore water in your YADE model, thus it is impossible with this model to access a pore water pressure. -- You received this question notification because your team yade-users is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp

New question #665564 on Yade: https://answers.launchpad.net/yade/+question/665564 Hey Guys! I wrote up a script for CU triaxial but I do not know how can I get EXWP (Excess pore water pressure) from my model. Hence, I would like to as you how can I get it or there is any way for it?
