How to change direction of rotaion of Radial Mchine
 

Hi everyone,

I want to do 2D simulation of Radial Turbine and want to change the direction of the rotation of my radial machine. i tried to do that by putting negative value for angular velocity in Pre processor. But didn't work out for me. Since i
am interested in Anti-clockwise roatation of impeller and It always show clockwise rotation in Post processor.

Any suggestion would be great in this concern.
