how to access to the face value of VOF of each cell
 

Hello folks,
I am trying to write a UDF for mass transfer rate for VOF equation, but I couldn't find the macro to access the face value of VOF of each cell and C_VOF only reply the cell value of VOF. Can anyone help me with it?
I appreciate.:)

There is a macro F_VOF, but this one works only for boundary faces, otherwise F_VOF=C_VOF

Thank you for your reply! You mean Fluent doesn't provide the access to the face value of VOF except the cell on the boundary. Oh,that's too bad.
