Hi Guys,

I've a convection problem between wall and tube. There are three solids contacting eacg other. I've adapted contacting surfaces. There are concection boundry condition on both side of wall and inside of tube. For the same B.C. the reference temperature on the pipe and heat flux through the interface are rising with element number. I think element number should be sufficient. I attached model and the results according to node number, what could be my mistake ?
