Hi there, I have been experiencing a recurrent issue when trying to run simulations. Error #61, no input elements found, appears. However, in another thread of the forum explains why that happens, the elements have this "^" symbol in front of them, which excludes them from the solver. In my case that issue appears when I export my session from Optistruct (preprocessing) to Basic FEA and I try to run the study. In Basic FEA all the rigids (RBE2) and geometry I create gets suppressed with that "^" symbol and when I try to rename the components to avoid the exclusion from the solver, it just does not allow me to do so. I rename the component but it switches back to its old name with "^". Also, I tried to use the option of creating rigids with the option of Rigid Body on Line/Surface, and it works but using that I cannot bond several rigids and I cannot place the load where I want to. On the other hand if I navigate to Mesh > Create > 1D elements > Rigids I can create them but they would get suppressed with this "^" symbol again. Same happens with geometry and the auto property that Optistruct creates when you do not select material and so on because it is going to be applied in Basic FEA anyways. I tried several thing to get this to troubleshoot this issue but I have been quite unsuccessful, can I have some piece of advice? Thanks.
Hi, I ran the optimization solver using optistruct with basic point loads as a test. However when i apply the display von mises stress on simple averaging method, there is nothing. It seems to be running fine with no errors so I don't understand whats happening. see picture attached output file spit out this: 1 MaxDisp 1240140 0.00000 0 1 MaxStress 0 0.00000 0 2 MaxDisp 60 0.282330E-01 0 2 MaxStress 31836 -496.786 0 3 MaxDisp 3886 -0.411211 0 3 MaxStress 32798 3767.72 0 4 MaxDisp 65 -0.137933 0 4 MaxStress 12682 1697.60 0 5 MaxDisp 65 0.00000 0 5 MaxStress 12682 0.00000 0 6 MaxDisp 63 -0.815247E-01 0 6 MaxStress 12682 754.470
