Curl-Flow: Boundary-respecting pointwise incompressible velocity interpolation for grid-based fluids
Chang, Jumyung; Partono, Ruben; Azevedo, Vinicius C.; Batty, Christopher (Association for Computing Machinery, 2022-12)We propose to augment standard grid-based fluid solvers with pointwise divergence-free velocity interpolation, thereby ensuring exact incompressibility down to the sub-cell level. Our method takes as input a discretely ... -
Preserving Geometry and Topology for Fluid Flows with Thin Obstacles and Narrow Gaps
Azevedo, Vinicius C.; Batty, Christopher; Oliveira, Manuel M. (Association for Computing Machinery, 2016-07-01)Fluid animation methods based on Eulerian grids have long struggled to resolve flows involving narrow gaps and thin solid features. Past approaches have artificially inflated or voxelized boundaries, although this sacrifices ...
