From 6677820431f5567f5f44acbe7ec6b76c6290aed0 Mon Sep 17 00:00:00 2001 From: Gustavo Marques Date: Tue, 10 Sep 2019 14:52:52 -0600 Subject: [PATCH] Updates layer_fluxes_bulk_method and bulk_average Many updates to allow the boundary layer to intersect a layer. Commented out some of the unit test previously added as the API has changed. These need to be revisited later. --- src/tracer/MOM_boundary_lateral_mixing.F90 | 241 ++++++++++++--------- 1 file changed, 144 insertions(+), 97 deletions(-) diff --git a/src/tracer/MOM_boundary_lateral_mixing.F90 b/src/tracer/MOM_boundary_lateral_mixing.F90 index 4ff8292403..b9c53e6655 100644 --- a/src/tracer/MOM_boundary_lateral_mixing.F90 +++ b/src/tracer/MOM_boundary_lateral_mixing.F90 @@ -17,7 +17,6 @@ module MOM_boundary_lateral_mixing use MOM_remapping, only : average_value_ppoly, remappingSchemesDoc, remappingDefaultScheme use MOM_tracer_registry, only : tracer_registry_type, tracer_type use MOM_verticalGrid, only : verticalGrid_type -use polynomial_functions, only : evaluation_polynomial, first_derivative_polynomial implicit none ; private @@ -38,29 +37,52 @@ subroutine boundary_lateral_mixing() end subroutine !< Calculate bulk layer value of a scalar quantity as the thickness weighted average -real function bulk_average(h, hBLT, phi) - real, dimension(:), intent(in) :: h !< Layer thicknesses [m] - real , intent(in) :: hBLT !< Depth of the mixing layer [m] - real, dimension(:), intent(in) :: phi !< Scalar quantity +real function bulk_average(boundary, h, hBLT, phi, ppoly0_E, ppoly0_coefs, method, k_top, zeta_top, k_bot, zeta_bot) + integer :: boundary !< SURFACE or BOTTOM [nondim] + integer :: nk !< Number of layers [nondim] + integer :: deg !< Degree of polynomial [nondim] + real, dimension(nk) :: h !< Layer thicknesses [m] + real :: hBLT !< Depth of the mixing layer [m] + real, dimension(nk) :: phi !< Scalar quantity + real, dimension(nk,2) :: ppoly0_E(:,:) !< Edge value of polynomial + real, dimension(nk,deg+1) :: ppoly0_coefs(:,:) !< Coefficients of polynomial + integer :: method !< Remapping scheme to use + + integer :: k_top !< Index of the first layer within the boundary + real :: zeta_top !< Distance from the top of a layer to the intersection of the + !! top extent of the boundary layer (0 at top 1 at bottom) [nondim] + integer :: k_bot !< Index of the last layer within the boundary + real :: zeta_bot !< Distance of the lower layer to the boundary layer depth + !!
