Kelvin-Helmholtz instability - Pseudo Spectral Simulation on GPU [4K]

Numerical Simulation of the Kelvin-Helmholtz instability using the pseudo-spectral method. The code is incompressible but a dye rendering module was applied to illustrate the flow motion. Code : Resolution: 2000*1500*4 Re: 100000 Run Time: ~8 Hours using RTX3080
