Hi all, If I specify my impeller speed as 100 RPM, does the CFX5.6 solver take this to be clockwise or anticlockwis rotation??

thanks Omondi

Hi Omondi,

Use the right hand screw rule which hopefully you remember from your undergraduate physics and vector maths. The direction given by this rule around the axis you define is positive.
