scripts/requirements.txt for dependencies| Input | Description | Example |
|---|---|---|
Grid spacing dx | Spatial discretization | 0.01 m |
Time step dt | Temporal discretization | 1e-4 s |
Velocity v | Advection speed | 1.0 m/s |
Diffusivity D | Thermal/mass diffusivity | 1e-5 m²/s |
Reaction rate k | First-order rate constant | 100 s⁻¹ |
| Dimensions | 1D, 2D, or 3D | 2 |
| Scheme type | Explicit or implicit | explicit |
| Physics | Number | Explicit Limit (1D) | Formula |
|---|---|---|---|
| Advection | CFL | C ≤ 1 | C = v·dt/dx |
| Diffusion | Fourier | Fo ≤ 0.5 | Fo = D·dt/dx² |
| Reaction | Reaction | R ≤ 1 | R = k·dt |
Multi-dimensional correction: For d dimensions, diffusion limit is Fo ≤ 1/(2d).
