selectCode()

void selectCode	(	int	code,
		int	dof = 1 )

Select nodes having a given code for a given degree of freedom.

Parameters

[in]	code	Code that nodes share
[in]	dof	Degree of Freedom label [Default: 1]

selectCoordinate()

void selectCoordinate	(	real_t	x,
		real_t	y = ANY,
		real_t	z = ANY )

Select nodes having given coordinates.

Parameters

[in]	x	x-coordinate that share the selected nodes
[in]	y	y-coordinate that share the selected nodes [Default: ANY]
[in]	z	z-coordinate that share the selected nodes [Default: ANY]

Coordinates can be assigned the value ANY. This means that any coordinate value is accepted. For instance, to select all nodes with x=0, use selectCoordinate(0.,ANY,ANY);

unselectCode()

void unselectCode	(	int	code,
		int	dof = 1 )

Unselect nodes having a given code for a given degree of freedom.

Parameters

[in]	code	Code of nodes to exclude
[in]	dof	Degree of Freedom label [Default: 1]
