 August 20, 2009, 08:26 How to set Temperature as heat source in Solids #1 New Member   Shahid Parvez Join Date: Jul 2009 Location: Pakistan Posts: 25 Rep Power: 8 Hi I am a new user of CFX and will be very thankful if can help in a very simple problem. I have a solid Rod of radius 1.2 mm and length 2mm with temperature about 3000k. Argon is flowing around the rod and simulation is required to see the temperature rise in Argon. I tried to follow the tutorial "Conjugate heat transfer in a Heating Coil" but I know the temperature and not the energy source. How to apply temperature in my case? Regards Shahid

This is straightforward. If you know the temperature of the rod then you don't need to model it. Model the fluid region with a cutout for the the heating rod. Put a specified temperature of 3000K on the rod and other boundaries to generate the rest of the flow. This is a straightforward single domain simulation.

I think that is what hamed was trying to say but I couldn't make most of it out.
