Ansys Fluent | How to Plot Graph? | XY Plot
Written by cfd.ninja
An XY plot is how you turn a colourful contour into a number you can defend. Instead of judging a result by eye, you extract the variable along a line, a surface or a boundary and look at its actual distribution.
The workflow is always the same: create the surface where you want the data, choose the variable on the Y axis, choose what to plot it against on the X axis, and decide the direction vector that orders the points. A velocity profile across a channel, the pressure along a pipe wall, the temperature through a solid: all of them are the same operation with different surfaces.
Two habits pay off. Export the data to a file so you can compare runs or plot it elsewhere, and place your lines at positions you can compare against theory or experiment, not wherever the geometry happens to be convenient.
