 Concerning the boundary conditions, all the "walls" of the plate are coupled and I also set the initialization of the solid ( patch : température 27°C for the plate)  so the heat flux at the plate's walls is 0 for the both simulation (steady and transient). Moreover, I also created a boolean during the geometry with the air of the oven as target body and the plate as tool body and I don't know if it can be linked to my problem.
