Hello. I was doing a simulation of a pressure vessel. When I tried to get the results, I got the following error:
^^^ USER FATAL MESSAGE 9137 (SEKRRS)
^^^ RUN TERMINATED DUE TO EXCESSIVE PIVOT RATIOS IN MATRIX KLL.
^^^ USER ACTION: CONSTRAIN MECHANISMS WITH SPCI OR SUPORTI ENTRIES OR SPECIFY PARAM,BAILOUT,-1 TO
^^^ CONTINUE THE RUN WITH MECHANISMS.
Does anyone knows how to correct this?
Assuming it is a SOL101, model does not have enough constraints to prevent rigid bodies or you have a mechanism ( beam attached directly to a solid or shell for example)
if still unsure then run a sol103 and you'll see what is not properly constrained
