Hey Guys, I'm attempting to run a simulation on a simple frame structure.
The frame is constructed from square hollow section weldments and the members are treated as beam elements.
A plate is welded to the top of the frame, this is treated as a solid body for meshing purposes.
8 joints of the frame have been selected as fixed geometry, and a remote load is applied to a set of bolt holes on the solid plate mentioned above.
The problem that I'm having occurs during meshing. For some reason or other, some of the frame members are lost and do not form part of the mesh, the leaves the simulation unsolvable as parts of the mesh are left dangling about in space.
I've attached a couple of screen shots of the model with and without the mesh visable.
Can anyone tell me why I'm missing some beams?
