Functions/Subroutines
subroutine, public	regrid_interp::regridding_set_ppolys (CS, densities, n0, h0, ppoly0_E, ppoly0_S, ppoly0_coefficients, degree)
	Given the set of target values and cell densities, this routine builds an interpolated profile for the densities within each grid cell. It may happen that, given a high-order interpolator, the number of available layers is insufficient (e.g., there are two available layers for a third-order PPM ih4 scheme). In these cases, we resort to the simplest continuous linear scheme (P1M h2). More...
subroutine, public	regrid_interp::interpolate_grid (n0, h0, x0, ppoly0_E, ppoly0_coefficients, target_values, degree, n1, h1, x1)
	Given target values (e.g., density), build new grid based on polynomial. More...
subroutine, public	regrid_interp::build_and_interpolate_grid (CS, densities, n0, h0, x0, target_values, n1, h1, x1)
real function	regrid_interp::get_polynomial_coordinate (N, h, x_g, ppoly_E, ppoly_coefficients, target_value, degree)
	Given a target value, find corresponding coordinate for given polynomial. More...
integer function	regrid_interp::interpolation_scheme (interp_scheme)
	Numeric value of interpolation_scheme corresponding to scheme name. More...
