Hi,
Does any body know how to find "centre of pressure" of an airfoil in CFX-post? I already have the pressure coefficient chart.
Thanks,

please define "centre of pressure". In case you are looking for the point of minimum or maximum pressure, you could create a point in Post and choose as Method 'Variable Minimum/Maximum' and select your pressure (coefficient) and your airfoil as location.

Nice, I looked it up, too. I somehow never needed to calculate the center of pressure before.
Well, this is what my search in this forum found:

Yes, that looks like a good thread. Also shows I don't always get it right first time round
