Hello there,


Does anyone know how to increase the number of digits in the polar output values of CL, CD, and CM calculated from XFoil? I want to calculate the gradients of CL, CD and CM values with respect to small perturbations of the geometry of an airfoil. However the gradient values are coming out to be zero since XFoil only outputs 4 digits after the decimal for CL and CM, and 5 digits for CD. However I would like to keep the upto 8 digits after decimals.


I read a similar post here , but couldn't get a relevant solution

Thanks!
