Generalized Non-Reflecting Boundaries for Fluid Re-Simulation

This work introduces non-reflecting boundary conditions with inflow/outflow constraints that vary arbitrarily throughout space and time. The approach allows seamless integration of fluid simulations into complicated environments, as well as post-process effects like retroactively changing the location of solid obstacles and locally enhancing a pre-existing simulation.

Preserving Geometry and Topology for Fluid Flows With Thin Obstacles and Narrow Gaps

This novel Eulerian fluid solver with enhanced support for thin solids and narrow flow regions based on a cut-cell grid relies on a new graph-based, topology-aware pressure solver and boundary-conforming interpolants for advection within general polyhedral cells.
