UDF: Some Questions

Nirupam Rohatgi

Can some body help me on following issues:

1) Can we hook UDF to an outflow surface. 'Fluent/Define/Boundary Conditions/Surface_Name/Set' does not open the window for attaching UDF to an outflow boundary.

2) Can we use two 'Define Macro's in one UDF. In that case how to name the 'Macro' because they will have same name as that of the *.c file. Or what is the rule for specifying the name argument in a 'DEfine Macro'.

Is it necessary to give name of UDF same as the name of the .c file containing the code.

3) Can we run face loop on a face that is different from the face to which UDF is being attached.

Thanks for the help.
