Status: Solved => Open Lei Hang is still having a problem: Hello, When I study the yade script about periodic simple shear test, I don't understand some places. The periodic simple shear script link is following: https://gitlab.com/yade-dev/trunk/blob/master/doc/sphinx/tutorial/04 -periodic-simple-shear.py I want to ask several questions: 1.What is the meaning of "O.cell.hSize=Matrix3(2,0,0, 0,2,0, 0,0,2)"? What is the meaning of the numbers in the Matrix? 2."pack.regularHexa(pack.inAlignedBox((0,0,0),(2,2,2)),radius=.1,gap=0,color=(0,0,1))". What is the meaning of the "color=(0,0,1)"? In some other scripts I also see "color=(1,1,1)" 3.What is the meaning of "O.cell.velGrad=Matrix3(-.1,0,0, 0,-.1,0, 0,0,-.1)"? What is the meaning of the numbers in the Matrix? In the "Checkstress()" part, it changes to "O.cell.velGrad=Matrix3(0,0,.1, 0,0,0, 0,0,0)" 4.What is the meaning of "O.cell.trsf[0,2]" in the "checkDistorsion" part? What do the numbers in the "trsf" mean? 5.In "plot.addData(exz=O.cell.trsf[0,2],szz=stress[2,2],sxz=stress[0,2],tanPhi=(stress[0,2]/stress[2,2]) if stress[2,2]!=0 else 0,i=O.iter)" part,What is the meaning of the number in the "streess[]"? For example, "stress[2,2]" or "stess[0,2]" Thank you very much for your kindly help! -- 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
