Subroutines

public subroutine uniformmesh(x1, x2, delta_x, n_x, x)

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=8),	intent(in)			::	x1	the left size of the mesh boundary
real(kind=8),	intent(in)			::	x2	the right side of the mesh boundary
real(kind=8),	intent(in)			::	delta_x	the largest element size
integer(kind=4),	intent(out)			::	n_x	the number of mesh elements
real(kind=8),	,		dimension(:), allocatable	::	x	the mesh midpoints

Description

creates a uniform mesh with size delta_x

public subroutine nonuniformmesh(x1, x2, delta_x, delta_x_min, n_x, x)

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=8),	intent(in)			::	x1	the left size of the mesh boundary
real(kind=8),	intent(in)			::	x2	the right side of the mesh boundary
real(kind=8),	intent(in)			::	delta_x	the largest element size
real(kind=8),	intent(in)			::	delta_x_min	the smallest element size
integer(kind=4),	intent(out)			::	n_x	the number of mesh elements
real(kind=8),	,		dimension(:), allocatable	::	x	the mesh midpoints

Description

creates a nonuniform mesh with size varying from delta_x_min on the left edge of the boundary to delta_x on the right edge of the boundary. The element sizes vary as \(\log\left(\frac{a}{a^{n}}\right)\)
