Access to arrays of Pressure matrix in CFX
 
Hi all
I'm trying to simulate flow over airfoil. this airfoil has a moving surface and the relation that specify mesh motion of this surface based on pressure distribution on surface. in this relation i need to access the arrays of pressure in this surface, such as pressure on a line on surface of airfoil. How can i do this?

Thanks, best regards.

Have a look at the rigid body motion example tutorials which come with CFX. You will need V13, it was not in previous versions.

Thanks for reply of my question ghorrocks,
How does it work in ansys 13?

As I said, have a look at the tutorials.

I studied that, but i can't find any things useful for my case. i need use pressure with argument as Pressure(x,y,z). for example pressure on each node of a line or edge in inlet. How can i do this?

Best regards.

How can i specify an expression that do this: the pressure on 0<x<2 and 0<y<2 saved to an expression ?( Pressure on each node of one surface)
