Modules
module	ppm_functions
	Provides functions used with the Piecewise-Parabolic-Method in the vertical ALE algorithm.

Functions/Subroutines
subroutine, public	ppm_functions::ppm_reconstruction (N, h, u, ppoly_E, ppoly_coef, h_neglect)
	Builds quadratic polynomials coefficients from cell mean and edge values. More...
subroutine	ppm_functions::ppm_limiter_standard (N, h, u, ppoly_E, h_neglect)
	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. More...
subroutine, public	ppm_functions::ppm_boundary_extrapolation (N, h, u, ppoly_E, ppoly_coef, h_neglect)
	Reconstruction by parabolas within boundary cells. More...

Variables
real, parameter	ppm_functions::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. More...
