I'm trying to make a surface approximation to describe the required input torque to drive a hydraulic motor operating under certain load conditions. My inputs are: output flow, output pressure and input shaft speed. I have scattered measurement data where the relationship between these variables are to be found. I read in some of the earlier posts that gridfit could be extended to higher-dimension fits. Do you have any version where a 3rd dimension can be included that I could try?
