Hi nice to meet you.
I am a freshman here, and i am a beginner.
I hope you understand my terrible english skills.

Now using ANSA (meshing) and ANSYS Fluent 13.0.

This picture is a fluid motion arround the solid rotor.

I did this in two ways.

First, i did with MRF ('Frozen rotor?') - rotate cell zone

Second, i did with Rotating only a boundary wall.


<Questions>

1. I am wondering what is the advantages/disadvantages
between two types.

2. What can i call the second type
ex) Rotating cell zone -> MRF ( Frozen rotor )
Rotating only a boundary wall -> ??


Thank you for reading my questions.
