Hello, How can I define mass flow rate at angle to inlet instead of normal to boundary condition. I have seen manulas about flow direction option but little confusion. The flow should enter the domain at angle with specific mass flow rate. Could any one help. Thank you.

Hii Vis,

Please share the solution for massflow with specifed angle

Either I am confused, or the original submitter did not express the question properly.

Mass flow by definition is the area integral of V.N; therefore, it is not even a valid question.

What is your goal? Perhaps someone in the forum can help sort it out.

If you want to specify the mass flow and the direction of the flow, it implies you are specifying the velocity normal component implicitly

Hope the above helps,
