Mass sources and sinks for multiPhaseFoam

newbee

Hi,

I have a circular channel confined between two coaxial pipes, created with the help of the wedge BC. In this channel I want to create a gas phase at the inner of the coaxial pipes as if the liquid turned in to gas phase.

In order to do this I need to create a mass sink for the liquid and a mass source for the gas. I guess that its the alpha.H file in twoPhaseEulerFoam that I need to alter. Does anyone have a tip for me how to do this modification?

Thanks
