Hi,
I am new at turbo modeling in fluent. I need to model a 3D rotor blade, I did everything correct except boundary conditions. I do not know which zone or surface should be rotating and I do not know how to choose between relative and absolute.
fluid: rotating/stationary/absolute/relative?
blade:rotating/stationary/absolute/relative?
hub:rotating/stationary/absolute/relative?
Shroud:rotating/stationary/absolute/relative??

can anybody give me a little help?
thanks

Hi
fluid:relative and in rotational reference and specify the rpm.
blade:stationary
hub:stationary
Shroud:stationary

this will give you result you want.
