Can you modify the attached file to show what output you are referring to? I do not know of extra output generated by AUTOMSET... maybe you have a param set?
Only one PARAM in the model: PARAM,AUTOMSET,YES. AUTOMPC is in the case control as AUTOSPC(NOPRINT)=YES. It's a standard SOL103 (actually written out of APEX).
Do you want to open up a regular technical support case? I think you are going to have to send me a sample that shows this behavior... maybe we can do a WebEx so I can see what is going on. I modified my sample to be sol103 and had an RBE3 along with the RBAR and it doesn't give that output. What version of Nastran are you running?
