momentum source term for new generated mass source

      Hi, All,


      In ansys user guide manual, it says "energy and momumtum source terms should be defined for new generated mass source in the domain. Otherwise, new generated mass should be accelerated and heated by existing mass, which causes inaccurate results"


      I am wondering how should I define momemtum source and energy source for new generated mass source? Does the new generated mass has same velocity and temperature with existing mass?


      Best regards

      You can use the local velocity and temperature to get the secondary source terms.

      But if you are introducing at another temperature or momentum you should then do it accordingly
