      Hi all,


      is it possibile to have a time dependent heat source like this?

      Hello, 


      Yes, it is possible. 


      Regards,

      And do I have to do the derivation like I did?

      No, you can put in anything you want. However, I find it best to use a sensible value.

      and if you work with a volume of fluid model, is there a way to apply this heat source only to one phase? 


       


       


      Kind regards

      In VOF you have single temperature equation so the weighting with volume fraction would only make sense for interracial cells (from one to N cells depending on the scheme).

      Your UDF is wrong.

      What would you suggest to solve the problem of heating source in one fluent in a 2 phase model?
