chtMultiRegionSimpleFoam: colling a thin film
 

Hi,
i attached a picture of a simplified heat exchanger. There is a thin (40µm = 0,04mm) film made from polyamide to be cooled with air. The thin film runs with speed in z direction (notice the coordinate system) through the heat exchanger. The film should be cooled with air. Can i have a solid body (the polyamide film) moving with velocity throught the heat exchanger? I think that will only work with fluids. Next, How do i mesh the thin film? Regards, fanta
