Hi everyone,
I'm modeling a 3D beam using PIPE31 elements to represent a pipe (defined with Beam Section). The beam is fully fixed at the top (all 6 DOFs), and there is no contact in the model — just a single beam structure with self-weight.
When the pipe is vertical, the simulation runs without any issues. However, when I incline the beam, I get the following warning during the solution:
*Solver problem. Numerical singularity when processing node TUBING-1.1678 D.O.F. 2 ratio = 10.E+09 .
*Solver problem. Numerical singularity when processing node TUBING-1.1119 D.O.F. 2 ratio = 100.E+09 .
Has anyone experienced something similar? Could this be related to disconnected nodes, or a geometric issue when inclining the beam? Any ideas or suggestions would be greatly appreciated.
Thanks in advance!
