fluidbe

fluidbe is a fictional open-source software framework designed to simulate and visualize fluid dynamics in interactive applications, such as educational tools, games, and research prototypes. The project emphasizes accessibility, modularity, and real-time performance. fluidbe provides a core solver engine that can run 2D and 3D simulations using multiple numerical methods, including lattice Boltzmann and smoothed-particle hydrodynamics, with optional incompressible flow approximations. It includes a scene graph and rendering pipeline for visualization, as well as a plugin system that allows researchers and developers to add custom solvers, boundaries, and post-processing effects. The framework offers Python bindings and a C++ core, along with cross-platform support (Windows, macOS, Linux) and GPU acceleration via OpenCL or CUDA where available.

Development and status: The concept emerged from academic demonstrations in the early 2020s and has since been used in teaching materials and demonstration projects. While fluidbe is not a standard in the field, its design has influenced discussions on modular CFD tooling and didactic visualization.

Applications and reception: In education, fluidbe is used to illustrate how boundary conditions affect vortices and mixing. In entertainment and rapid prototyping, it provides a sandbox for experimenting with fluid effects. Critics note that as a fictional project, it lacks a formal governance model and production-grade stability; real-world users may rely on established CFD libraries for research-grade results.
