recon1d_eppm_cwk module reference¶

Piecewise Parabolic Method 1D reconstruction in model index space with linear extrapolation for first and last cells.

Data Types¶

eppm_cwk

PPM reconstruction in index space (no grid dependence) with linear extrapolation for first and last cells.

Functions/Subroutines¶

`reconstruct()`	Calculate a 1D EPPM_CWK reconstructions based on h(:) and u(:)
`unit_tests()`	Runs EPPM_CWK reconstruction unit tests and returns True for any fails, False otherwise.

Detailed Description¶

This implementation of PPM follows Colella and Woodward, 1984, using uniform thickness and with cells resorting to PCM for local extrema. First and last cells use a PLM representation with slope set by matching the edge of the first interior cell.
