Question #669006 on Yade changed: https://answers.launchpad.net/yade/+question/669006 De zhang posted a new comment: Dear RCaulk, Thank you for your reply~ You are right that I was trying to make a cubical simulation of triaxial test. Howerver, My purpose is to work on nonsphere assembly, so the TriaxialStressController may not work as it can only deal with the contact of sphere. I found that problem of 'command=''' or O.engines+PyRunner(command='...') will cause other situations, I am doubt that wether my code of using '.command=' and 'PyRunner' were right?

You appear to be controlling the triaxial stresses of a cubical specimen manually through python. Am I right? Is there a reason you are not using the thoroughly tested and efficient TriaxialStressController [1]?

New question #669006 on Yade: https://answers.launchpad.net/yade/+question/669006 Hi, Recently I wrote a code for traxial simulation.
