Hi Guys.
I am simulating a gas-liquid system with ANSYS-CFX and i want to set mass flow boundaries with fractional mass flux specifications in my work.
I cant find this kind of boundary in mass and momentum option.
I am waiting for answer my question...

It is definitely possible, you can specify it with wall velocity component combined with mass souce term.

thank you windhair for your help,but i want to set this kind of boundary condition in liquid outlet,not wall.Do i need mass flux for this boundary?
I have just amount of outlet velocity.
another my question is about mass source term in sources tab.at this part it requests me mass flux volume fraction and i dont know what value i have to use.
its useful to know that in the liquid outlet bondary exist just liquid.
