Grid Spline

Overview

Cabana::Grid provides the B-Spline related interfaces for interpolation with uniform grids. The supported orders are:

• 0 — Nearest Grid Point Interpolation
• 1 — Linear
• 2 — Quadratic
• 3 — Cubic

Implementation

Cabana_Grid_Splines.hpp

Examples

• Spline Unit Test
• Spline Evaluation Unit Test

Usage

    using value_type = double;
    constexpr int order = 2;

    Cabana::Grid::SplineData<value_type, order, Cabana::Grid::Node> sd_n;
    Cabana::Grid::evaluateSpline(local_mesh, x, sd_n);
