I am new to comsol. Can any one tell me whether the following geometry can be modeled for conduction (transient) heat transfer? I want to see the temperature changes at different time steps. Please help.

It can be modeled.

Thanx. Can it be modelled using the existing equations in Comsol multiphysics? Because I am unable to model it using numerical schemes such as FDM.

I have created the model in 3D but the problem is I can't put the powdered bed inside the vessel. Please look at pic and suggest where I am going wrong.

The following figure is my 2d geometry without the metal powder bed. I am having problem setting up the problem. Mainly defining the boundary conditions. The outer shell is of steel and its in 350C (exposed to 350C hot air). I am unable to get the temperature profile of the structure at different time steps. The fins are at 30C initially. What is the best way to describe this boundary condition?? can anyone help me please.
