Function/Subroutine Documentation

m_grid_construct()

type (m_grid_class) function, pointer m_grid::m_grid_construct	(	character (len=*), intent(in)	mgrid_file_name,
		type (bmw_parallel_context_class), intent(in)	parallel,
		integer, intent(in)	io_unit
	)

Construct a m_grid_class object.

Allocates memory and initializes a m_grid_class object with an mgrid file.

Parameters

[in]	mgrid_file_name	File name for vacuum fields.
[in]	parallel	bmw_parallel_context_class object instance.
[in]	io_unit	Unit number to write messages to.

Returns

A pointer to a constructed m_grid_class object.

m_grid_destruct()

subroutine m_grid::m_grid_destruct

(

type (m_grid_class), pointer

this

)

Deconstruct a m_grid_class object.

Deallocates memory and uninitializes a m_grid_class object.

Parameters

[in,out]

this

A m_grid_class instance.

m_grid_interpolate()

pure subroutine m_grid::m_grid_interpolate	(	type (m_grid_class), intent(in)	this,
		real (rprec), intent(in)	r,
		real (rprec), intent(in)	phi,
		real (rprec), intent(in)	z,
		real (rprec), intent(out)	ar,
		real (rprec), intent(out)	ap,
		real (rprec), intent(out)	az
	)

Interpolate the vector potential at a point.

This interpolates the vector potential to from the mgrid grid to an arbitrary point. This performs a trilinear interpolation.

Parameters

[in]	this	A m_grid_class instance.
[in]	r	Radial position to interpolate to.
[in]	phi	Phi position to interpolate to.
[in]	z	Vertical position to interpolate to.
[out]	ar	Interpolated radial component of the vector potential.
[out]	ap	Interpolated phi component of the vector potential.
[out]	az	Interpolated vertial component of the vector potential.
