## Detailed Description¶

Piecewise constant reconstruction functions.

## Function/Subroutine Documentation¶

subroutine pcm_functions/pcm_reconstruction(N, u, edge_values, ppoly_coef)

Reconstruction by constant polynomials within each cell. There is nothing to do but this routine is provided to ensure a homogeneous interface throughout the regridding toolbox.

It is assumed that the dimension of ‘u’ is equal to the number of cells defining ‘grid’ and ‘ppoly’. No consistency check is performed.

Parameters
• n :: [in] Number of cells

• u :: [in] cell averages

• edge_values :: [inout] Edge value of polynomial, with the same units as u.

• ppoly_coef :: [inout] Coefficients of polynomial, with the same units as u.
