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.
Removed shell offsets to no avail.
Then I selected all faces to probe for the elusive element number 43144. I have a hard time believing there is a problem with that element considering that there are only 28,000 elements in the model.
Well I got the study to run. It may have had something to do with applying a virtual wall and grounding bolt fixtures to surface bodies. I removed these fixtures and applied a simple fixed face constraint and the simulation ran without issue. I have since converted the surfaces in question back into solids which has allowed me to re-apply my grounded bolt fixtures.
I have not come across this error before but I am not yet running 2011. If you want you can upload your model and I can take a look.
I also had this error. I was creating small cylinders to represent bolts and representing them as 2d beam elements (same as I use to perform in Algor) and I would extract the beam forces in axial and shear to calculate the FOS using the elliptical interaction equations. The problem is the length of the beam is not at least the same as the diameter this error pops up. When I reduced the diameter of the bolt cylinder I was able to run the simulation without the error.
I had the same error - after reading this thread I took note of Joe's comments and removed the bolted connections in my model (I added some bonded connections to make up for the missing bolts) the model ran fine, suggesting that the problems are occuring within the bolted connection. My scenario had a solid body sandwiched between two surface bodies that were bolted together.
Fine for me as we can just run calcs for the bolts at that point - it was other points in the frame were were really interested in. Not sure where this leaves other peoples studies though.
