Hello,

whenever I try to solve this model, consisting of different element types, I get this error: "There is at least 1 small equation solver pivot term (e.g., at the ROTX degree of freedom of node 138)."

I assume it is due to not connected beam-solid element interfaces. How is the connection properly done? It shall be fixed. A code snippet for APDL would be great.

Thanks in advance!
