The featured image displays plots of a CGNS dataset representing a YF-17 jet aircraft. The dataset consists of an unstructured grid with solution. VisIt created the image using a pseudocolor plot of the dataset's Mach variable, a mesh plot of the grid, and vector plot of a slice through the velocity field. VisIt 1.5 and later can read CGNS files.
The dataset was provided by the CGNS user community's Example Files page.
