Module gpu_fluid 

GPU-accelerated fluid simulation using a MAC (Marker-and-Cell) grid.

This module provides a CPU mock of GPU Navier-Stokes incompressible fluid simulation. The MAC grid stores pressure at cell centres and velocity components on cell faces, following the Harlow-Welch staggered layout.

Structs

FluidObstacle

A rigid obstacle embedded in the fluid grid.

FluidSimGpu

High-level GPU-accelerated fluid simulation driver.

MacCell

A single cell in a Marker-and-Cell (MAC) grid.

MacGrid

A 2-D Marker-and-Cell (MAC) grid for incompressible fluid simulation.

VorticityConfinement

Vorticity confinement adds back dissipated rotation energy.

Functions

cfl_timestep

CFL-stable time-step for the MAC grid.

interpolate_velocity

Bilinearly interpolate velocity at world coordinates (x, y).

reynolds_number_grid

Compute the Reynolds number Re = u_max * L / nu.
