Transient Weissenberg Effect Visualization (Rod-Climbing)

A simple animation simulating the transient rod-climbing effect typical of viscoelastic fluids using built-in MATLAB graphics.

This script provides an illustrative, GPU-friendly animation of the Weissenberg effect (rod-climbing phenomenon) typically observed in polymer systems and viscoelastic fluids. When a rotating rod is inserted into such a fluid, normal stress differences cause the fluid to climb up the rod, defying gravity.

Important Note

This is a phenomenological graphical visualization, not a quantitative Computational Fluid Dynamics (CFD) solver.
