Hi everyone. I'm trying to run a buckling analysis on a model that has a lot of stiffened plates, where the plates are modeled with CQUAD4's and the stiffeners are CBEAM's with offsets.
When I try to run the linear buckling solution (SOL 105), I get a fatal error for each offset element that...
A little background: I have about 8 years of experience, but all of my experience has been with static analysis of structures. I recently started a new job where I'm responsible for both static and dynamic analysis including analysis of drive trains.
I've been doing a lot of normal modes...
Has anyone ever had a problem with not being able to see MPC's in Patran?
I'm working with a model that I'm been using for some time. I just upgraded to 2012 and now I can't see the RBE2's that are there. I can highlight and select them with the mouse, so I know they are there, but they won't...
Hi all,
This is my first post in this forum.
I have a problem that I'm not sure how to approach. I'm going to be doing an structural and thermal analysis of an engine exhaust system. The scope of work specifies that I need to consider "exhaust gas induced vibrations." Does anyone have any...
Hi all,
I'm trying to mirror RBE2's in Patran 2011, and I can't find a way to do it. Finite Elements > Transform > Element > Mirror won't let me select MPC's. Neither will Utilities > FEM Transform...
I just spent a lot of time modeling half of a symmetric structure with the assumption that...
Hi all, this is my first thread here.
In the past I've used symmetry constraints to only model a portion of a structure when running a static analysis. I just want to make sure that there are no other considerations or "gotchas" when using that approach with dynamics or modal analysis...
