Mass & Momentum sources

Kittu · January 26, 2017, 11:01

I want to know whether a inlet pipe with certain velocity can be given in the domain without creating a geometry. Mass source need a geometry to provide a static pressure and velocity at the inlet but my inlet diameter is very small compared to my domain. Mass momentum source will vary the flow rate and make my source into sink during simulation. I would like to know if there is any way to give a constant velocity inlet without geometry using mass momentum source. Help !!!

You can use mass-momentum sources. In the flow specification, select 'Velocity', and then enter the component values.
