Data Types

mplm_cwk

PLM reconstruction following Colella and Woodward, 1984.

Functions/Subroutines

reconstruct()

Calculate a 1D PLM reconstructions based on h(:) and u(:)

check_reconstruction()

Checks the MPLM_CWK reconstruction for consistency.

unit_tests()

Runs PLM reconstruction unit tests and returns True for any fails, False otherwise.

Detailed Description

This implementation of PLM follows Colella and Woodward, 1984 colella1984, except for assuming uniform resolution so that the method is independent of grid spacing. The cell-wise reconstructions are limited so that the edge values (which are also the extrema in a cell) are bounded by the neighbors. The first and last cells are always limited to PCM.
