Hi Anwer,
at the moment we don't have any official material, which we can give you for learning.
We have done this in the past for a customer, but we can not simply hand this work out.
But if you like to learn about feature programming, you can write your own features in order to change raterateshape profiles, based on parameters like nozzle diameter or number.
I guess you have seen the tutorial about piston bowl modeling, which discribes also the connection to Converge.
If you have more specific questions, please let me know.
Best regards
Carsten
