Hello,

I have a question about solid works simulation. I want to model a cylinder that
is closed on both sides. Inside the cylinder there is a heat source [Watt] which
is surrounded by air. The heat source will heat the air inside the cylinder.
The air will heat the cylinder and the cylinder is cooled through convection on
its outside. I am interested in the temperature of the cylinder at a specific
time, so I need to run a transient simulation.

I do not know how to simulate
the air inside the cylinder, does anybody know how this is done?
