body force eulerian model

davoudj · July 20, 2017, 10:33

hello friends
I want to know how I can apply magnetic field as external body force in eulerian model???
in mixture it appear in slip velocity parameter
in Homogenous we can add it as source term in Momentum equation
thanks all

Hi bro, have you figured out your problem? I am facing the same thing with you

davoudj · May 5, 2018, 03:41

hi
you can apply your udf source term on both or one of phase
my case was nanofluid and i apply my source term on second phase in x and y direction.

Thank you davoud, but I can't find a source term in the momentum equation in the Theory Guide. Are you sure that it works? I mean, adding a momentum source in some of the cell zones?

yes, I sure
you can add your source term in momentum equation and it work.
maybe it can help you:
