Source Point injection

Sebastian

Hello guys,

i am trying to simulate dye inserting to a mixing vessel. The aim ist to inject a certain amount of dy from a source point directly to the flow ( I m using the additional variable approach). But at the moment i m having two problems: (I should mention that i m using a rotating domain and dont have any baffles or other stuff creating turbulence....just a typical mixing experiment)

1. How can I give a direction to my dye when im inserting threw a source point? is it possible to use the continuity equation? Or is it only working for a multicomponent flow.?

2. How can i avoid that the source point ist rotating? Ist it possible to use sth like the frozen rotor for one domain ?

I would realy appreciate some help
