Question #263739 on Yade changed: https://answers.launchpad.net/yade/+question/263739
Status: Open => Answered Jérôme Duriez proposed the following answer: Performing isotropic compression moving the walls at a constant rate is still possible: you just have to switch internalCompaction to false (*) (it is true by default) As for the rate part, using stressMask = 7, the appropriate attribute to set is max_vel (**). Basically, for stress controlled behavior of TriaxialStressController, this engine tries, moving the walls with internalCompaction=0, to reach the desired stress value in one iteration. But, without exceeding a wall velocity of max_vel... Then, if you want to iso-compress your sample to some pressure significantly different from the initial one, just use stressMask=7, internalCompaction=0, and max_vel=someValue, and you will perform an isotropic compression at a constant strain rate corresponding to someValue >From my point of view, there is no reason to consider all these attributes related to final results rather than intermediate steps.
