The cylinder is made from 303 Steel, so the cylinder would not burst. The top temperature would not surpass 800K.

But a heat comparison between different grades of steel, aluminium etc may be viable.

This is a static problem and would use no motion.

I have ansys yes. My project will remain the same I just want to use some ansys to analyse the cylinder.

I wonder if it be a better option to CFD at two different points (Statically) - where the displacer is in the heated region, and then when the piston is in the cold region, just to look at pressure variations. This may simplify it.
