ppm_functions real, parameter real, parameter ppm_functions::hneglect_dflt hneglect_dflt = 1.E-30 A tiny width that is so small that adding it to cell widths does not change the value due to a computational representation. It is used to avoid division by zero. This is a dimensional parameter and should really include a unit conversion. ppm_boundary_extrapolation subroutine, public subroutine, public ppm_functions::ppm_reconstruction (N, h, u, edge_values, ppoly_coef, h_neglect, answers_2018) ppm_reconstruction N N h h u u edge_values edge_values ppoly_coef ppoly_coef h_neglect h_neglect answers_2018 answers_2018 Builds quadratic polynomials coefficients from cell mean and edge values. n Number of cells h Cell widths [H] u Cell averages [A] edge_values Edge values [A] ppoly_coef Polynomial coefficients, mainly [A] h_neglect A negligibly small width [H] answers_2018 If true use older, less acccurate expressions. ppm_limiter_standard mom_remapping::build_reconstructions_1d regrid_interp::regridding_set_ppolys mom_remapping::remapping_unit_tests mom_ale::ts_ppm_edge_values subroutine subroutine ppm_functions::ppm_limiter_standard (N, h, u, edge_values, h_neglect, answers_2018) ppm_limiter_standard N N h h u u edge_values edge_values h_neglect h_neglect answers_2018 answers_2018 Adjusts edge values using the standard PPM limiter (Colella & Woodward, JCP 1984) after first checking that the edge values are bounded by neighbors cell averages and that the edge values are monotonic between cell averages. n Number of cells h cell widths (size N) [H] u cell average properties (size N) [A] edge_values Potentially modified edge values [A] h_neglect A negligibly small width [H] answers_2018 If true use older, less acccurate expressions. regrid_edge_values::bound_edge_values regrid_edge_values::check_discontinuous_edge_values ppm_reconstruction subroutine, public subroutine, public ppm_functions::ppm_boundary_extrapolation (N, h, u, edge_values, ppoly_coef, h_neglect) ppm_boundary_extrapolation N N h h u u edge_values edge_values ppoly_coef ppoly_coef h_neglect h_neglect Reconstruction by parabolas within boundary cells. n Number of cells h cell widths (size N) [H] u cell averages (size N) [A] edge_values edge values of piecewise polynomials [A] ppoly_coef coefficients of piecewise polynomials, mainly [A] h_neglect A negligibly small width for the purpose of cell reconstructions [H] hneglect_dflt mom_remapping::build_reconstructions_1d regrid_interp::regridding_set_ppolys mom_remapping::remapping_unit_tests mom_ale::ts_ppm_edge_values Provides functions used with the Piecewise-Parabolic-Method in the vertical ALE algorithm.
