wich program for internal flow / diffusor and ...
 

I must choose a program for a firm who produced papermachines. They would optimize some things like diffusor and Headbox.

I want use the sst model. All the "big three" known this model. But for the optimization the calculation must be fast and exact. Important are good secondary flows and boundry layer.

What in your opinion is the best program for these things. Had someone a benchmark wich can help me?

sorry for my bad englisch.
