This really brought back memories and put a smile on my face. My Master's thesis was writing a fluid simulation on the GPU, also using OpenGL (with all work done in GLSL fragment shaders) and also restricting simulation to 2D (because I was specifically simulating fluid running across a surface). The most interesting thing to me was how much this article resonated with my own experiences in GPU-based particle simulation. I instead went for a particle-based method and had to make do with the state of GPU hardware and drivers as they were back in 2011. But despite the difference in computational model and all the differences stemming from the evolution of GPUs and compute shaders, the main struggles are still the same: discretization and parallelization.
