move together don't have a perfect thermal coefficient

move together don't have a perfect thermal coefficient

Hello ,

i am at the end of my modeling of a satellite structure but i can`t find how to model a specific connection.

I want two surfaces ( one by solid , one by shell) that touch each other to be joined kinematically ( no move between them ) and thermally have a conduction tha it is pressure depented .

Many thanks
Konstantinos

RE: move together don't have a perfect thermal coefficient

Your question is too broad to get a cognitive response. Please re-state your question with more detail about what you want to accomplish and how.

You are right it was my first post so i didn´t know how analytical it should be .
Lets try again smile

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 now it is more clear
Thanks a lot
