Tie mechanically - pressure dependent conductunce .

Hello,

it is the third day i am working on this and i hope someone could help

I am doing a thermomechanical analysis at a satellite construction . I have two surfaces ( one solid and one shell ) that in reality are going to be either glued or connected with a screw . Because it is not clear yet , i agreed with my supervisor to do a connection that mechanically ''ties'' the two surfaces ( makes them as one body ) and thermally we have a pressure-depented conductance . The shell surface is touched tottaly , the solid surface only a small part of the hole surface .

I am trying to do with a surface to surface contact with cohesive behaviour and thermal conductance that it is pressure depented , but the job is completed with a lot of Warnings when the coductance is low and for big conductance it says ''too many attempts for this increment'' .

I hope it is clear enough , if not i am w8ing for questions
Thanks a lot
