Any Integration Algoritms?
 

Hi, I am wondering how to integrate data points. What i am trying to do is to get my lift and drag forces from my airfoil simulation. for that, i need to integrate pressure dx ,wall shear stress dy, etc. But i cannot use the simpson's integration algorithm because i have variable steps. do u have an algorithm to recommend besides the trapezoidal rule?

You can use the Simpson method with nonuniform grid. Look at the zip file in the following link to see how it is performed
