Hello all, I am trying to load a femur model according to a local coordinate system. When loading in the non-desired direction for testing (Z-dir) the model node moves predictably. But when I try to load in the desired direction against the springs (X-dir), the model does some crazy twisting and weird movement. Would love some help resolving this issue. I have a suspicion it may have to do with the springs... making them very compliant still didn't solve my issue though. .fem files attached 6_25_Altair_Question.zip
Dear all, I searched in the forum for similar questions but found nothing that could help me solving my following problem: I have built a tube forming simulation (not Hyperform) using a roll-bending process. All of the tools are stationary accept the so called forming roll. The forming roll has 2 dof: the bending-arm angle and the displacement (radial to the rotational center of the bending-arm). To define the movement of the forming roll I have chosen a cylindrical coordinate system. Since the loadcollectors do not change their coordinate definition when using cylindrical Systems, I do not know how to correctly define the coordinate directions. I have defined the following: - beding arm-angle is the rotation around ZZ axis of the cylindrical system (which is working as I want it to) - the displacement of the forming roll has to be done in radial direction but parallel to the fixed cylindrical System with a distance of X (this is not working, i tried several definitions but the forming roll is never moving towards the tube) The best way to solve this problem would be to define two coordinate systems: the first one is fixed and the second one is local (moving) and parallel to the first one with a distance of X (in global X direction). The center of the second system has to rotate around the center of the first system. The displacement of the forming roll has to be done in Y direct of the local moving second system. Could somebody help me defining this? Therefore I attached the *.rad files of my model. Thank you very much and best regards Kerschten DRSB_003_0000.rad DRSB_003_0001.rad
Dear all, I have a problem defining the right connection between a rigid and a spring (please find a picture attached). I want to design a simultaneous movement of a Part by rotation around global zero and translation along a spring (translational KJOINT). My Problem is how to connect SPRING2N and RBODY to ensure no relative movement in the connection point. Also attached is a test-model of the problem. Thanks so much!
