Question #687294 on Yade changed: https://answers.launchpad.net/yade/+question/687294
Status: Open => Answered Jan Stránský proposed the following answer: Hi, first, check if the **body** is there, interaction comes afterwards. E.g. by executing O.step() # after it, the wall is not visible in GUI print(U_box.state.ori) # full of NaNs, interaction detection does not work then.. to solve this, either block rotational degrees of freedom U_box.state.blockedDOFs = "XYZ" or set nonzero inertia U_box.state.inertia = (1,1,1) cheers Jan -- 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
