I'm using sheet metal for a buckling analysis with fastener holes on each side of the panel. I want to add forces in the longitudinal direction of the panel and I want simply supported boundary conditions as well on the sides where the fasteners are located. The top and bottom of the panel are free edges. I applied x, y, and z constraint on the surface of the fastener holes and then applied x and y constraints on the right side. I think this should allow the panel to deform how I want it to. I thought that I would be able to apply my forces on the fastener holes on the right side in the z direction seeing as the only constraints on that side are in the x and y directions, but it seems like there is a problem with the constraints I've added. I've reviewed what I did in a similar exercise where I add constraints on the edges of the panel, and not on the fastener holes, and that worked but this model doesn't seem to like what I want to do.
