- 3. Modeling laminated glass as a Beam When you want to model a composite material if you sketch like this shape, ansys consider whole shape as one body. In order to solve this issue, I suggest to follow these steps: 1.Draw whole shape 2.Define virtual plane in appropriate elevation 3.Extrude the shape 4.Use Slice and virtual plane for cutting the shape.
