flow number calculation
 

Hello :

I need to calculate flow number for a stirred tank. The procedure is to create a cylindrical surface around the impeller and then calculate the flow going out of the cylinder. I already have a converged flow field. How do I proceed from there ?

I understand that I will have to write a utility for it. Can anyone suggest me the right utility to start with ( a utiilty doing something similar )

Regards,
Kedar
