CFluid

Terminal-based 2D fluid simulator

Prerequisites

  • A very fast terminal emulator supporting 24bpp colors (e.g., Alacritty). Normal ones like macOS Terminal and GNOME Terminal will not cut it.

  • A fast, unmetered network connection to the host machine if you want to run it remotely over SSH (not recommended due to excessive network traffic generated).

  • rustup to build the program.

Usage

# Monotone particles (use mouse to disturb)
cfluid

# Monotone particles on very thick fluid
cfluid -v 1e5

# Particles with trails colored by velocity
cfluid --heatmap velocity --trails

# Cool screensaver
cfluid --heatmap velocity --trails -s
