differentiation-schemes

separate

Select and apply numerical differentiation schemes for PDE/ODE discretization. Use when choosing finite difference/volume/spectral schemes, building stencils, handling boundaries, estimating truncation error, or analyzing dispersion and dissipation.

When to use

• choosing finite difference/volume/spectral schemes
• building stencils
• handling boundaries
• estimating truncation error
• analyzing dispersion and dissipation
• discretization of PDE/ODE

When not to use

• **Boundary handling**: Stencil generator provides interior stencils; boundaries need special treatment
• **Nonuniform grids**: Standard stencils assume uniform spacing
• **Spectral**: Not covered by stencil generator
