recon1d_ppm_hybgen module reference

Piecewise Parabolic Method 1D reconstruction following Colella and Woodward, 1984.

Data Types

ppm_hybgen

PPM reconstruction following White and Adcroft, 2008.

Functions/Subroutines

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

Detailed Description

This implementation of PPM follows Colella and Woodward, 1984 [17], with cells resorting to PCM for extrema including first and last cells in column. The algorithm was first ported from Hycom as hybgen_ppm_coefs() in the in the mom_hybgen_remap() module. This module is a refactor to facilitate more complete testing and evaluation.module. This module is a refactor to facilitate more complete testing and evaluation.

The mom_hybgen_remap.hybgen_ppm_coefs() function (reached with “PPM_HYGEN”), function (reached with “PPM_HYGEN”), regrid_edge_values.edge_values_explicit_h4cw() function followed by function followed by ppm_functions.ppm_reconstruction() (reached with “PPM_CW”), are equivalent. Similarly (reached with “PPM_CW”), are equivalent. Similarly recon1d_ppm_hybgen() (this implementation) is equivalent also. (this implementation) is equivalent also.
