      Hello everyone, I'm trying to perform a simple 2D axisymmetric analysis in mechanical. Everything works fine until I'm trying to obtain the 3D version of the total velocity (or any variable) with symmetry. The mechanical suddenly crashed for some reason with no error messages. I managed to obtain the same error with the following trivial analysis

      Is this not allowed for Eulerian frames? Because the symmetry works fine with Lagrangian frames. Will appreciate any help, thanks in advance.

      Hello

       

      I would suggest to post this in the LS-Dyna (Autodyn) forum.

      /forum/forums/forum/discuss-simulation/ls-dyna/

      All the best
