airfoil
 

hi, i face some problems on my work on cfx for my graduation project because i couldnt find the center of pressure or finding the moment on the airfoil around its center of pressure at (0) angle of attack because i think it calculates the torques around the global axis while i want to calculate torques around the center of pressure. i would be so grateful if you replied as soon as possible. thanks

Hi,

It is a trivial matter to transpose the global axis for torque to any axis you like. Just needs a little bit of easy physics. Look in the CFX reference manual for the available CEL expressions to help you do this.
