I would like to reproduce results from a much older code to test a new one. I only have the old code's results in the form of plots, not data, but I need data. The older code solves the unsteady vorticity transport equation in 2D with a constant kinematic viscosity term. I'm interested in 2-D tank-like geometries with inlets and pipe-like outlets. The original code uses a finite element method, but I'm not picky. It would be great not to have to write code to do this. The problem seems straightforward enough that I expected to find codes/applets online, but so far I don't see anything. A Matlab script with plotting capabilities would be great, but I'll try anything. Could anyone help?
