As far as I know the general answer is no. If you are using elastic elements you need to assign directly Area and Inertia. Therefore you do not mind the shape. If you are using nonlinear elements, then in the case of fiber sections (e.g.) you need to assign the shape, whether rectangular or circular...

Dear all, I have unsuccessfully tried to run a nonlinear static analysis with displacement control for a simple beam in a four point bending test configuration. The model has 4 nonlinearbeamcolumn elements between five aligned nodes. The first and fifth nodes are the supports, while the second and f...
