A Second-Order, Variable-Resolution, Weakly-Compressible Smoothed Particle Hydrodynamics Scheme
Abhinav Muta, Pawan Negi, Prabhu Ramachandran
The smoothed particle hydrodynamics (SPH) method has been widely used to simulate incompressible and slightly compressible fluid flows. Adaptive refinement strategies to dynamicall…
