  3. Why does Contact Tool Initial Information sometimes report a different bonded contact status than the Contact Tool under Solution Branch after solve is complete? It should not change for bonded contact.

      One possible explanation is that CNCHECK,,used to generate initial information assumes NLGEOM,off. If the final solution is run with NLGEOM,on, some of the contact tolerances might be different. Check Real constant #25 for one possible difference. It can be manually set with RMODIF,cid,25,2 to match large deflection default if necessary. This particular inconsistency has been addressed in R2022-R1.
