Detailed Description

Class to construct a list of nodes having some common properties.

This class enables choosing multiple selection criteria by using function select... However, the intersection of these properties must be empty.

◆ selectCode()

void selectCode ( int  code,
int  dof = 1 
)

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

Parameters
[in]codeCode that nodes share
[in]dofDegree 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]xx-coordinate that share the selected nodes
[in]yy-coordinate that share the selected nodes [Default: ANY]
[in]zz-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]codeCode of nodes to exclude
[in]dofDegree of Freedom label [Default: 1]
