Hi!! I´m simulating the aerodynamics of my own car, and i want know how i can find out the CoP in Altair Hyperworks CFD 2022.3. Anyone can help me??Thanks very much!!
Javi.
I believe you'll need to create a variable (using the Calculate tool) for pressure * X, then use the integration tool to integrate that quantity on the surface in question. (The expression would be
pressure * coords[:,0]
Then also Integrate the pressure on the surface in question.
Center of Pressure (in X) = Integral ( pressure * X ) / Integral ( pressure )
then similar for other dimensions, Y and Z.

Hi! First of all, thanks you ver much to help me!Following your steps I have done this:
and then, I use Integration to the car surface
And now I have to divide, right? but divide Average or Sum?Thanks for all!!Javi

The sum and average are different by the factor of the area. So whether you use the Sum column or the Average column, the result will be the same.
