New question #685539 on Yade: https://answers.launchpad.net/yade/+question/685539
Hi everyone, I can't understand the logic of the orientation standards for Potential Block, in particular for blocks with oblique facets. I respected all the explanations from the answers to this question: https://answers.launchpad.net/yade/+question/685375 but I see some problems specially for blocks having oblique facets as for third blocks in the simple example, below. for converting a convex block to PB, I do in this way: 1-compute center of block 2-calculate new vertex coordinates with local center 3-calculate a,b,c,d for all faces 4-(d-chosenR) for all d s what gives me the output data same as below example, but when I try to create PB, it works without problem for (straight) block, but for blocks with oblique faces, they are misdirected. I don't know why? Thanks a lot Best regards Ali ################ a simple example chosenR=0.0001 ################################ PB parts #Number of facets # center of block # a ax+by+cz+d=0 # b # c # d 6 0.0 3.0 0.0 1.0 -0.0 -1.0 -0.0 -0.0 -0.0 0.0 -1.0 0.0 1.0 -0.0 -0.0 0.0 -0.0 -0.0 -0.0 1.0 -1.0 0.9999 1.9999 0.9999 1.9999 0.9999 0.9999 6 0.0 4.0 3.0 1.0 -0.0 -1.0 -0.0 -0.0 -0.0 0.0 -1.0 0.0 1.0 -0.0 -0.0 0.0 -0.0 -0.0 -0.0 1.0 -1.0 0.9999 0.9999 0.9999 0.9999 1.9999 1.9999 9 0.6733279600737498 3.79366976022725 6.1040638685226245 0.4233422835886639 -0.0 -1.0 -0.0 -0.0 -0.2544435504552162 -0.0 0.2256157225428006 0.7071067811865475 -0.4658182304526213 -1.0 0.0 1.0 -0.0 -0.0 0.2924660204513265 -0.5965652970583126 -0.0 -0.4658182304526213 0.0 -0.0 -0.0 1.0 -0.8250734563293101 -0.12273156061799324 -0.4512314450856012 -0.0 0.9630391247904834 1.20623023977275 1.83734355291125 0.79356976022725 1.1039638685226245 1.2066387820121347 0.3419810759564882 0.7092731583297133 1.5290583284351422 6 0.0 0.0 0.0 1.0 -0.0 -1.0 -0.0 -0.0 -0.0 0.0 -1.0 0.0 1.0 -0.0 -0.0 0.0 -0.0 -0.0 -0.0 1.0 -1.0 1.9999 0.9999 1.9999 0.9999 0.9999 0.9999 ########################################### -- 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
