Thanks aerostress82, that actually seems to be the problem. Before I read your post I changed the contact type from bonded, which in my understanding is the stiffest possible contact, to frictional, and the red spots ceased to appear. Reading your post confirms it. I was a contact problem!

That's what I thought initially. In fact, the peak stresses don't appear at spots where singularities should present. But they are there and don't converge to finite values. I refined the mesh further and max stresses climb even more abruptly. I have already tried to remake the CAD model with...
Here's one image of the model in isometric view with applied forces and bc'shttp://files.engineering.com/getfile.aspx?folder=84acd632-3129-4be9-a8d5-03d5e97a9246&file=Screenshot_3.jpg
Hi there!
I have been reading some posts on eng-tips about singularities, so the reason I am posting this thread is that I can't quite understand what type of singularity I'm getting on my analysis. I suspect there is one because as i refine my mesh, the maximum value for the von-mises stress...
