Hello, I have just started with Sofistik. I want to perform an analysis of A rectangular steel beam (material S355), length 3m, which is supported on both sides by pinned support, and there is a point load of 5KN in the middle point (L/2). The cross-section has a height of .02m and a width of .20m. I have written the follow teddy code but its not working. Can you please help me with it what is the problem here.
