This tutorial provides step-by-step instructions for performing many basic post-processing operations – especially those relevant to computational fluid dynamic analysis. After successfully completing this tutorial you should be able to create a clipping plane and display contours and vector arrows on the plane, move the clipping plane with the mouse, create an isosurface and change the isovalue interactively, create a single particle trace and a rake of traces and save an image of the Graphics Window to a file.
