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.
