I'm worked to analyse the stresses in a truss structure. During the mesh, rigid links of some kind are being inserted into my model, they appear to be one continous beam element. They've appeared in location where there are NO beams and in other locations they're appearing not-quite parallel to existing beams. If I run the simulation, these member are definately affecting the results, there are stress concentrations at the connection points of these ghostly members.
Any ideas what these are?
How can I make them disappear?
I'm doing a pack-n-go and rebuilding the simulation from scratch currently...
