Function Documentation

void pragmatic_2d_init	(	const int *	NNodes,
		const int *	NElements,
		const int *	enlist,
		const double *	x,
		const double *	y
	)

Initialise pragmatic with mesh to be adapted. pragmatic_finalize must be called before this can be called again, i.e. cannot adapt multiple meshes at the same time.

Parameters

[in]	NNodes	Number of nodes
[in]	NElements	Number of elements
[in]	enlist	Element-node list
[in]	x	x coordinate array
[in]	y	y coordinate array

Definition at line 71 of file cpragmatic.cpp.

void pragmatic_3d_init	(	const int *	NNodes,
		const int *	NElements,
		const int *	enlist,
		const double *	x,
		const double *	y,
		const double *	z
	)

Initialise pragmatic with mesh to be adapted. pragmatic_finalize must be called before this can be called again, i.e. cannot adapt multiple meshes at the same time.

Parameters

[in]	NNodes	Number of nodes
[in]	NElements	Number of elements
[in]	enlist	Element-node list
[in]	x	x coordinate array
[in]	y	y coordinate array
[in]	z	z coordinate array

void pragmatic_adapt

(

)

Adapt the mesh.

Definition at line 190 of file cpragmatic.cpp.

void pragmatic_add_field	(	const double *	psi,
		const double *	error,
		int *	pnorm
	)

Add field which should be adapted to.

Parameters

[in]	psi	Node centred field variable
[in]	error	Error target
[in]	pnorm	P-norm value for error measure. Applies the p-norm scaling to the metric, as in Chen, Sun and Xu, Mathematics of Computation, Volume 76, Number 257, January Set to -1 to default to absolute error measure.
