Hi all, Is there a way to increase the number of integration points (IPs) along the length of a beam element (Note: I am not trying to increase the number of IPs on a cross-section). For...

Hi all, This is a straightforward model and I have no idea why it is not converging. In the model, I applied a concentrated load on one end of the column with the other end pinned. I had run this...
