Detailed Description

Boundary conditions mechanisms for cell scalars.

This directory contains several types of routines:

routines to apply explicitly boundary conditions and fill boundary ghost cells.
routines to compute explicitly quantities on physical boudaries

Function Documentation

◆ apply_bc_on_ghost_b_cells()

subroutine mod_apply_bc_on_ghost_b_cells::apply_bc_on_ghost_b_cells	(	double precision, dimension(:,:,:), intent(inout)	array,
		type(t_boundary_condition), intent(in)	boundary_condition )

Apply boundary conditions on extra ghost cells on an array defined on cells.

Parameters

[in,out]	array	an array defined on cells
[in]	boundary_condition	bondary_condition

◆ compute_uncentered_boundary_cell_gradient()

double precision function mod_compute_uncentered_boundary_cell_gradient::compute_uncentered_boundary_cell_gradient	(	double precision, intent(in)	t0,
		double precision, intent(in)	t1,
		double precision, intent(in)	t2,
		integer, intent(in)	boundary )

Compute field gradient at a global physical boundary.

The field gradient at a global physical boundary is computed using second-order accurate Lagrange polynomials. For instance, the following sampling is used at the left boundary:

 values:   t0  t1      t2
           ├───×───┼───×───┼──
 indices:      is    is+1

or at the right boundary:

 values:                       t2      t1  t0
                         ──┼───×───┼───×───┤
 indices:                    ie-1      ie

Compute uncentered second order cell gradient on a boundary

◆ exchange_periodic_ghost_cells_rank3_double()

pure subroutine mod_exchange_periodic_ghost_cells::exchange_periodic_ghost_cells_rank3_double ( double precision, dimension(:,:,:), intent(inout) array )
