How can I put the heat flux into a solver?
 

According to the turtoial, there are only variables about temperature, pressure, and the velocity. But I want to put heat flux in the replacement of the temperature, how can I do this?
Thank you!

Hello,

maybe you are looking for this:

Then you can specify the heat flux you want. It will take into account the molecular and turbulent thermal diffusivities. There is also a compressible version.
