hole in geometry model

      Hi, I want to model a circular hole in a rectangular model using AUTODYN with axial symmetry. However, I don’t see any tools for this operation. Could you please advise?

      Hello,

      Could you elaborate on the model? For instance, does your model include an existing hole, and is your goal to leverage symmetry by modeling only a portion, such as 1/4 of the geometry (Please refer to the picture below.)

      Hi, I want to do circle holes in ma rectangular 2D geometry, bellow I attach a schem. In upper part i am going to do 1/4 cirle hole and use axial symetry.

      Please refer to the screenshot below for instructions on how to insert a 'Symmetry Region' and assign it to the appropriate edges of the model. Note that the 'Symmetry Normal' must be selected carefully to ensure proper consideration of symmetry.
