Functions/Subroutines
program	__m_weno_fpp_f90__
subroutine	s_initialize_weno_module
	The computation of parameters, the allocation of memory, the association of pointers and/or the execution of any other procedures that are necessary to setup the module.
subroutine	s_compute_weno_coefficients (weno_dir, is)
	The purpose of this subroutine is to compute the grid dependent coefficients of the WENO polynomials, ideal weights and smoothness indicators, provided the order, the coordinate direction and the location of the WENO reconstruction.
subroutine	s_weno (v_vf, vl_rs_vf_x, vl_rs_vf_y, vl_rs_vf_z, vr_rs_vf_x, vr_rs_vf_y, vr_rs_vf_z, norm_dir, weno_dir, is1_weno_d, is2_weno_d, is3_weno_d)
subroutine	s_initialize_weno (v_vf, norm_dir, weno_dir)
	The computation of parameters, the allocation of memory, the association of pointers and/or the execution of any other procedures that are required for the setup of the WENO reconstruction.
subroutine	s_preserve_monotonicity (v_rs_ws, vl_rs_vf, vr_rs_vf)
	The goal of this subroutine is to ensure that the WENO reconstruction is monotonic. The latter is achieved by enforcing monotonicity preserving bounds of Suresh and Huynh (1997). The resulting MPWENO reconstruction, see Balsara and Shu (2000), ensures that the reconstructed values do not reside outside the range spanned by WENO stencil.
subroutine	s_finalize_weno_module ()
	Module deallocation and/or disassociation procedures.

private

The computation of parameters, the allocation of memory, the association of pointers and/or the execution of any other procedures that are required for the setup of the WENO reconstruction.

Parameters

v_vf	Cell-averaged variables
vL_vf	Left WENO reconstructed cell-boundary values

s_preserve_monotonicity()

subroutine __m_weno_fpp_f90__::s_preserve_monotonicity ( real(wp), dimension(idwbuff(1)%beg:, idwbuff(2)%beg:, idwbuff(3)%beg:, 1:), intent(in) v_rs_ws, real(wp), dimension(idwbuff(1)%beg:, idwbuff(2)%beg:, idwbuff(3)%beg:, 1:), intent(inout) vl_rs_vf, real(wp), dimension(idwbuff(1)%beg:, idwbuff(2)%beg:, idwbuff(3)%beg:, 1:), intent(inout) vr_rs_vf )

private

The goal of this subroutine is to ensure that the WENO reconstruction is monotonic. The latter is achieved by enforcing monotonicity preserving bounds of Suresh and Huynh (1997). The resulting MPWENO reconstruction, see Balsara and Shu (2000), ensures that the reconstructed values do not reside outside the range spanned by WENO stencil.

Parameters

i	Equation number
j	First-coordinate cell index
k	Secone-coordinate cell index
l	Thire-coordinate cell index
