This lesson covers the postprocessing of cell center values of primary unknowns in Ansys Fluent® fluid simulation software to produce useful visualizations. The lesson explains how to use its postprocessor to visualize velocity vectors, contour plots, and pressure contours. The lesson also demonstrates how to create and visualize total pressure contours, total temperature contours, and mock number plots. The video further explains how to improve the resolution of these plots by increasing the sampling points.
