Unsteady vorticity transport equation: codes available?

Click For Summary
SUMMARY

The discussion centers on the need for a code to reproduce results from an older simulation of the unsteady vorticity transport equation in 2D, specifically for tank-like geometries with inlets and pipe-like outlets. The original code utilized a finite element method, but the user is open to alternatives. They express a preference for a Matlab script with plotting capabilities, while also inquiring about the applicability of OpenFOAM for this purpose. The user aims to validate new calculations against the results of the older code.

PREREQUISITES
  • Understanding of unsteady vorticity transport equations
  • Familiarity with finite element methods
  • Basic knowledge of Matlab scripting
  • Awareness of OpenFOAM capabilities and limitations
NEXT STEPS
  • Research Matlab scripting for fluid dynamics simulations
  • Explore finite element analysis tools compatible with vorticity transport
  • Investigate OpenFOAM for potential adaptations to vorticity transport equations
  • Review literature on 2D tank-like geometries in computational fluid dynamics
USEFUL FOR

Researchers and engineers in fluid dynamics, computational fluid dynamics practitioners, and anyone looking to reproduce or validate simulations of unsteady vorticity transport equations.

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?
 
Have you tried OpenFOAM? Also, why vorticity transport and not NS?
 
Thanks. I want to reproduce calculations from an old report to test some new calculations. As far as I know, OpenFOAM doesn't have this approach.
