I have been at this assembly for a couple of weeks.  I have turned off "Large displacement" and "Compute free body forces".  I have turned on "Use soft spring to stabilize model". 

Usually, I get a Large Displacement error, I click yes, and it gives me a displacement result, and I bond the displaced object.  Now, I only get the "Numerical difficulties" error, and no Large Displacement error.  What do I do now?

Thanks,
