Detailed Description

Geometrical methods for level sets.

This module provides several methods for geometrical operations for level sets, such as:

• volume fraction
• normal
• curvature computations.

Function Documentation

compute_levelset_gradient_inline()

subroutine mod_lsm_normal::compute_levelset_gradient_inline	(	class(t_levelset), intent(inout)	my_levelset,
		integer, intent(in), optional	order )

Compute the level set gradient.

Note

also allocates the inner array in the LS object

compute_levelset_gradient_outline()

subroutine mod_lsm_normal::compute_levelset_gradient_outline	(	class(t_levelset), intent(in)	my_levelset,
		double precision, dimension(nx,ny,nz,spatial_dimension), intent(inout)	gradient,
		integer, intent(in)	order )

Compute the level set gradient.

compute_levelset_inplace_normal_only()

subroutine mod_lsm_normal::compute_levelset_inplace_normal_only	(	class(t_levelset), intent(inout)	ls,
		logical, intent(in)	do_compute_norm )

Compute the normal associated to the level set. The result is stored inside the levelset type.

Parameters

[in,out]	ls	The input/output levelset (nx,ny,nz)
[in]	do_compute_norm	Do compute or not the gradient's norm

compute_levelset_normal_only()

subroutine mod_lsm_normal::compute_levelset_normal_only	(	class(t_levelset), intent(in)	my_levelset,
		double precision, dimension(:,:,:,:), intent(inout)	normal,
		double precision, dimension(:,:,:), intent(inout), optional	gradient_norm,
		integer, intent(in), optional	order )

Compute the normal associated to the level set.

Parameters

my_levelset	The input levelset (nx,ny,nz)
normal	The output normal (nx,ny,nz,:)
gradient_norm	The output gradient's norm (nx,ny,nz,:)
order	The (optional) order of the method
