Hi all,

I'm trying to export the convection coefficient from CFX-post.

My configuration is simple : a solid immersed in water.
The configuration is a like-2D, which means that i've created a 3D from a 2D with a thin thickness, and with BC symmetry on all the opposite faces.

For now what i've done is to create a line at the wall of my solid, and export "heat transfert coefficient".

Now i want to see the difference in convection coeff value if the solid temperature changes. But then i'm facing a big issue :

How can I fixed the temperature of the solid (and no the walls of the solid) in CFX (without using a source power) ?


If anybody can help, it 'll be truly appreciated !!

Bye,

Hugo

Why do you even need the solid in there? Why not just have the fluid walls at a fixed temperature?

Make sure you read the FAQs on heat transfer coefficient in CFX, it isn't what you think by default.
