Ansys Fluent exporting ascii in rotating plane

LohengrinVB · February 18, 2021, 12:19

Hi,

I am running a simulation of a rotating cylinder in "frame motion".

I would like to export data from a centerplane at standstill in the rotating frame.

Plane creation seems only possible using coordinates in the standstill "absolute" frame.

Is there an elegant way to create and export from a plane: moving in the standstill frame / stationary in the rotating frame?

Sketch attached.

Thanks!

Hello,

By 'rotating frame', do you mean you would like to export the data in cylindrical coordinates?

Hi aero_head,

Thanks for the message.
Exporting the data in cylindrical or cartesian coordinates is not the problem.

I want to create a plane that also rotates, whereas the "plane creation" tool in fluent makes a plane that has an absolute velocity of 0.

Regards!
