im working on axial dispersion (one column) and want to correlate it (my correlation is a power law function) to two other variables (two different columns). When i launches the non linear curve fitting, an error message appears: "too many bad data points or functional evaluations".
From what I understand, you are defining a user defined function of two variables. An example would be z=sin(p1/x)+cos(p2/y). You need to set the Form to Equation in the Form drop-down list within the NLSF. I believe that this is causing the error.
