here I have attached a bridge structure with I beams. I keep getting the "solver pivot error", I have tried adding a modal into workbench and trying to see which beam components/ deformations were giving me the error. Also, I have tried under solution (A6) and analysis shutting off the solver pivot checking. Which I think helped a little bit because allowed me to solve but I see where the problem is to the left portion of the beam I don't think the beams are connected. How do I go back and fix this connection or ultimately this error pivot message to get the solution of total deformation I am looking for?

Thanks!
