Draw an approximation of it that will behave like a beam - how is the program suppose to know what I or length to use for this thing? It doesn't look like a beam. Draw something that does and put it in your model.
I need to solve that geometry using plane stress (1 cm thickness) assumption by restraining left hole and applying downward load on right hole - with beam elements.
Is it possible to solve this geometry in 2D with beam elements?
