Before revision: Computer simulation of fluid flow in the presence of complex geometries with mesh-free particle methods requires that the geometry be captured accurately . Methods like weakly-compressible and incompressiblesmoothed particle hydrodynamics (SPH ) perform better when the particle distribution is uniform.
After revision: Computer simulation of fluid flow in the presence of complex geometries with mesh-free particle methods requires that the geometry be captured accurately in terms of particles. In the context of incompressible/ weakly-compressible and incompressiblesmoothed particle hydrodynamics (SPH ) perform better when the particle distribution is uniform.
