OF and Cp

Hi guys,

Many external aerodynamics visuals use Cp as scalar. Can I generate these values directly from an OF function instead of calculating them in Paraview?

Thanks!

Hi,

Yes you can via a pressure functionObject. A preconfigured example can be found in:

Code:

$FOAM_ETC/caseDicts/postProcessing/pressure/staticPressure.cfg

For the coefficient you would have to change the line

Code:

calcCoeff     no;

to

Code:

calcCoeff     yes;

Thanks Tomf.

Also available as postProcess function, which is perfect for me.
