I am attempting a simulation on a chassis using pin joints to simulate slip joints and when I run the simulation I get an error that reads "Improper third node at BEAM element 128457". The number location is always different. Can anyone give me a tip on what this even means and how to solve it?
Thanks,

I am receiving this error as well. The odd thing about it is the error message references a BEAM element, however in my case the entire model is composed of shell elements. Perhaps the remote loads I'm applying are transferred using beam elements? What is really frustrating is that I can't figure out where the failing node is located in the model. Simulation lets you probe and it will tell you what node you picked, but as far as I can tell you can't specify a node number and have it show you the location.
At any rate, this is the first simulation I've set up since upgrading to SW2011. I've set up other studies in a similar fashion in 2010 and never saw this problem. I've tried different element sizes, selecting the other solver, and modifying the location of my remote loads to no avail.
The only thing I'm doing differently here is making use of the new offset setting in Shell Definition, as my model is comprised of thin-wall structural tubes and the surfaces are derived from the outer surface of those tubes, not the mid-plane.
In my case, the element number remains the same unless I remesh.
The solver status window behaves as follows:
Forming surface to surface bonding seems to complete successfully
Establishing Element Connectivity is where the error occurs.
I'm going to remove the offsets in shell definition and see if it helps. I'll let you know how it goes.
