Mass source term

[napken]

Hello,

I'm using the fuel combustion case and I want to add a source term for the mass equation of mixture (equation of rho) but density is not a transported variable. Does anyone know how to do it? Or how to add a mass directly to the mass flow not using cs_user_source_term?

Best regard!

Hello,

Which version of the code are you using ? There is a specific mechanism for mass source terms, and some examples in the code, but the system has changed between v6.2 and earlier versions.

Hi,

Thank you for your reply.
I'm using ver 5.0. Is it possible for this version? If yes, could you please tell me how?
Many thanks

Hello,

Yes, you should check the user documentation pdf, and the cs_user_mass_source_terms.f90 user example.
You will see in the example that the pressure term is used to store the mass flow (as there is no pressure mass source term).
