CFD analysis of heat exchanger
 

I am trying to do the analysis of a particular type of heat exchanger, I have 2 doubts basically,
1. How to use heat exchanger model in the analysis?
2. even in the simple heat equation model, the temperature residual is diverging so please tell me the problems, I am using a mesh with 0.99 skewness and the file with 0.97 skewness is of 3.45gb so it is impossible to generate a solution.
Tips welcome:confused:

Hi,

Can you give us more details on what you want to do exactly, what is the type of heat exchanger, what do you want to analyse ? Send an image of your geometry and mesh...
