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 [17], 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.
