Hi everybody

I modeled a piece of CFRP in Comsol with a thickness of about 2cm, I used the new module in Comsol 5.5 ( thermal stress in layered shells)

Everything has gone well but after the simulation completed I figured out the part related to the heat transfer in shells although I applied heat flux and temperature is still totally insulated!

so the result I get for the temperature variation is almost a constant function!

I'm so confused and really don't know how to deal with this problem!

can anyone help me with that?

thanks
