Sir, I have plotted two cases, one using polyline and intersection for whole lower nozzle wall, and second using line tool for divergent portion of lower nozzle wall.
I am not understanding what you meant by plot on wall with no polyline?
Yeah, I had checked domain extent in scale option of fluent it is same for all the cases. And also I am sure of the start and ending points of all the curve, as I have done duplication of box and just change the grid density. So rest of the things will always remain same.
Ok Sir, lets assume even that I have done some mistake somewhere else,
Still I want to know is it not possible to specify certain set of coordinates or points and plot the property value on those set of points in Ansys post processing. I think there should be some way to do this.
