Volume Fraction at boundary

pranab_jha · September 7, 2011, 20:16

Hello,

I want to change the volume fraction at the boundary for incoming fluid from 0 to 1 (that is changing the fluid entering at the boundary) using a UDF. Can somebody tell me how to do this?

This link tells me that I can use the DEFINE_PROFILE macro to change the volume fraction at the boundary. But the only macro available for this is the C_VOF which is applied on a cell thread and not a face thread.

Any suggestions?

Silly question. Got the answer. Nevermind folks
