Data Types

emplm_wa

Extraplated Monotonic PLM reconstruction of White and Adcroft, 2008.

Functions/Subroutines

reconstruct()

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

plm_extrapolate_slope()

Returns a PLM slope using h2 extrapolation from a cell to the left, in the same arbitrary units as the input values [A].

unit_tests()

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

Detailed Description

This extends MPLM_WA, following White and Adcroft, 2008 [87], by extrapolating for the slopes of the first and last cells. This extrapolation is used by White et al., 2009, during grid-generation.

Type Documentation

type recon1d_emplm_wa/emplm_wa

Extraplated Monotonic PLM reconstruction of White and Adcroft, 2008.

Type fields:

  • % reconstruct [procedure,private] :: Implementation of the EMPLM_WA reconstruction with boundary extrapolation.

  • % unit_tests [procedure,private] :: Implementation of unit tests for the EMPLM_WA reconstruction.

Function/Subroutine Documentation

subroutine recon1d_emplm_wa/reconstruct(this, h, u)

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

Parameters:

  • this :: [inout] This reconstruction

  • h :: [in] Grid spacing (thickness) [typically H]

  • u :: [in] Cell mean values [A]

function recon1d_emplm_wa/plm_extrapolate_slope(h_l, h_c, h_neglect, u_l, u_c) [pure]

Returns a PLM slope using h2 extrapolation from a cell to the left, in the same arbitrary units as the input values [A]. Use the negative to extrapolate from the cell to the right.

Parameters:

  • h_l :: [in] Thickness of left cell in arbitrary grid thickness units [H]

  • h_c :: [in] Thickness of center cell in arbitrary grid thickness units [H]

  • h_neglect :: [in] A negligible thickness [H]

  • u_l :: [in] Value of left cell in arbitrary units [A]

  • u_c :: [in] Value of center cell in arbitrary units [A]

function recon1d_emplm_wa/unit_tests(this, verbose, stdout, stderr) [logical]

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

Parameters:

  • this :: [inout] This reconstruction

  • verbose :: [in] True, if verbose

  • stdout :: [in] I/O channel for stdout

  • stderr :: [in] I/O channel for stderr
