Improved method for contouring on isoparametric surfaces

A general nonlinear interpolation procedure for contouring on any isoparametric surface was presented in a previous article. This method used standard isoparametric interpolation functions and a predictor method for tracing element contour lines. The method presented here extends the previous work by using a predictor-corrector method to trace element contour lines, thereby making the contouring algorithm more accurate
