Hi Robert: It appears there is only the single vertical restraint, so the entire frame will exibit Rigid Body Motion (RBM). Imagine you can slide the frame on the floor in two orthogonal directions since there's no restraints to prevent it (2 RBM degrees of freedom) and spin the frame around a vertical axis (1 RMB degree of freedom). The static solver does not like that so you can 1) add a minimum amount of point restraints parallel to the plane of the floor (such as at two corners) at the base of the frame like in the attached image, or 2) turn on "Soft Spring" option in the Properties of the study. The "Soft Spring' adds a very small stiffness to all nodes and helps to stabilize the structure from RBM.
Hope that helps. Either of these suggestions should allow the model to run, and you can adjust the point restraints to different corners to observe the deformations you want- Tony
