CPU-Based Semi-Lagrangian Advection for Viscous Incompressible Fluids on Adaptive Grids with GPU-Assisted Visualization
The paper proposes an efficient semi-Lagrangian scheme on a CPU for simulating two-dimensional viscous incompressible fluids with GPU-assisted visualisations. We solve the Navier-Stokes equations on a quadtree adaptive grid where certain cells are subdivided if the velocity gradient, along any of the axes, exceeds a ce...
