Hi,
I have to perform a linear static analyisis on an axisymmetric component. I meshed the section in the XZ plane using CTAXI elements and I applied PAXI property; the model is constrained at the bottom and I've manually written the PLOADX1 at the top, in order to simulate a traction force.
I want to evaluate the stress concetration in a particular region of the component, so I used different mesh sizes.
When I run the model, AUTOSPC locks the y translational motion (dof = 2) in some grids, because of error 2133: the grid x 'has no stiffness and is not constrained'.
I would kindly ask you some hints to fix the problem.
p.s. : I performed the check on the mesh (panel tools>check elem) and no error was found.
In order to check if the problem was related to the mesh, I kept the mesh, but I changed the element type in CTRIA, the property in PSHELL and I put FORCES instead of PLOADX1; when I run this analysis, autospc didn't added any spc. So, is the problem related to the axisymmetric elements / load?
Thank you so much for your help
