  Hello.
  
  Can I input the volumetric heat flux in CFX domain?
  
  I want to consider heat exchanger with only one fluid, so I have to input the heat flux data from the experimental results.
  
  I have the total heat flux data in dimension [kW].
  
  I want to input the data to entire fluid domain in dimension [kW/m^3]
  
  Can I input the data like that? How can I?
  
  Thank you.

  Hello,
  
  I am guessing you want to provide a Volumetric Heat Source and not a Surface Heat Flux.
  
  You can make use of Subdomain Approach in CFX. Once you create a subdomain, you can then provide your Energy Source.
  
  In CFX, you can also use Profiles from Tools->Initialize Profile Data.
  
  You can find more information in CFX documentation for both Subdomain and Profiles.

  Thank you for your reply.
  
  I have applied the Subdomain and Energy source to the domain, but in the CFD-post, its temperature didn't vary.
  
  I think the Energy source didn't applied normally,
  
  These are the settings I have inserted. I there any problem inserting the subdomain and heat source?
  
  Thank you in advance.
