DISPLAY4
2D Flow Graphics


DISPLAY4 is a FORTRAN90 program which creates graphics files from the output of one of the various FLOW programs.

Specifically, the FLOW programs are the family of FLOW5 and FLOW6. Each of these programs solves a 2D steady state incompressible flow problem, and writes out an element and a node file, describing the flow velocity and pressure in the region.

DISPLAY4 can read in the element and node file, and then create images of the flow region, nodes or elements, or contour lines of the pressure, or vector plots of the velocity. Other plots are also available.
