I have recently started using ansys 15 workbench and I have a problem in that I can't assign frictional contacts to my geometry. I have never had this problem before and assume it is not a license problem but the settings need to be changed? My only guess is that some non-linearity setting is...
After a few ways of modelling this I managed to get accurate results. However, as first anticipated I was not able to use the body - body to spherical constraint. Instead I set up a local axis at the spherical node, transformed it to the cylinder line of action and used a remote displacement for...
Thanks for your help. Prior to your post I turned on large deflections, weak springs and indeed the local axis of the spherical is central to the local axis of the spherical constraint. I'm awaiting results...
Globally the boundary conditions are correct. The problem is with the body to body...
What would you suggest regarding weak springs? Should I also have large deflections on?
I have managed to set up a model using contacts, but it is very expensive with regards to running time.
I'm analysing a structure which has a cylinder and both the rod ends have spherical constraints. Free rotation x,y,z but can react translational loads in x,y,z. These spherical constraints are not grounded and are within the structure itself. When I use a body to body spherical contact the...
