2. is it better to use vof or eulerian model
3. what is the recommended UDF in C format.
4. How to activate vof model properly in this case
5. Is there a need to set function hooks
6. the case is interpreted or compiled
7. is there any tutorial that may help

Awaiting for your kind help and support. Thanks...
