I don't understand what means "outer loop/inner loop contact", please explain.
If you have problems with contact convergence, check the definition of your SOURCE & TARGET regions, this is the main issue: check that mesh in both source & target regions is the most possible matching each other, this is critical, having matching meshes helps a lot to easy convergence.
Also check your mesh density, in contact regions the mesh should be refined, not coarse, and matching as much as possible.
Please note that almost all is explained & written in the NX NASTRAN manuals, read them with attention: the following picture tells you do not use ONLY ONE region for the whole model, is preferible to define many connectors with many regions if the geometry is changing sharply, OK?.
Also, check that every region has perfect mesh continuity, do not define islands inside regions, this maks the region inactive.
Thank you, I was able to get my model to converge after improving my mesh quality. I have seen the part of the Nastran manual referenced and have attempted to keep my mesh sizing as consistent as possible. I also had checked the normals for plate elements and expanded elements on regions to make sure all the elements I expected were shown. I have attached some info that explains outer and inner loops a bit.
