Pre-Meshed Crack

      Hello Experts ...


      I've modeled a quarter stiffend panel (with symmetry ) with a crack in its center. Then I choose a pre-meshed crack and select the crack tip 


      I have found in the details of pre-meshed an option of symmetry, should I put it yes or No ??

      The definition of the symmetry is shown below:


      "Symmetry: Specifies the crack symmetry about a line (in 2D analysis) or about a plane (in 3D analysis). The default is No."

      Since you have symmetric geometry (and crack), I would turn it to Yes.


       


      Bests,
