i did a harmoic analysis. i excited an surface with displacement. as a result i measured 2 surfaces. afterwards i calculated the direct relation between the two surfaces.
my fear is that the two surfaces will be narrowed together by an angle, whereby the distances around this angle are different and thus the displacement is different. this would distort the result, since i only need the displacement to each other.
Is it possible to extract two new points from the solution file, one at the top and one at the bottom of the observed surfaces to calculate the error?
