Jan Stránský proposed the following answer: Hi, > If I want to get the micro-stress field. except for the position and radius data for all the particles. what are the other variables I need to output? as you guessed, it is stress tensor of each body :-) > According to the code given on the official website above, so I need to output the id and use the bodyStressTensors to get the stress?? ID is not needed IMO (but does not hurt anything at the same time). You can output the stresses in one file with x,y,z,r or you can just use a separate file. Normally corresponding line fits together, ID is the line number. > or from this [2] reference (especially equation 39), I need to output all the contact force and contact point and do the cross product and the get the per particle stress. You can do this, but it just what bodyStressTensors computes, so less error prone would be to use the output of bodyStressTensors directly. It is not cross product, but tensor product [3] cheers Jan [3] https://en.wikipedia.org/wiki/Tensor_product -- 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 : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
