thread1183-196141: COSMOS Beam element

same happened to me in this thread, I am trying to analyze stresses over a traffic lamp which consist of 3 beams connected with rings and these beams are connected to a solid on the base, for three days I am getting the same problem or different ones when I change the settings for solver. When I check the stabilizator box just base remains and the result is unrealistic, I fixed my assembly correctly It doesnt move anyway but what can be the problem ?

RE: the iterative solver stopped PRECONDITIONER_FAILS_TO_FACTOR

Try it with the sparse solver. Sounds like insufficient boundary conditions.
