Symmetry in Ansys

  1. Aug 20, 2016 #1
    I am doing a 2D Ansys workbench simulation ,it is nonlinear simulation due to frictionless contact, there is symmetry in the shape so I used the symmetry option to reduce the computation time and it succeeded to converge after that I tried the simulation of the whole body but it always fails ! I think this is strange because as far as I know the symmetry only reduces the computation time and has nothing to do with the convergence, Am I mistaken ?

    The symmetry condition may also simplify your boundary conditions, because deformation results also have to be symmetric. You should take a hard look at your boundary conditions for the full model and make sure they correctly replicate the boundary conditions of your symmetric loading case.
