Detailed Description

This class implements an interface element that connects two nodes. In order to compute the normal and tangential direction of the slip plane, a reference node or specific direction can be specified in the input. If neither are specified, then the normal direction are computed from the coordinates of the element's nodes. The class adjusts dimensionality automatically to 1D, 2D, or 3D depending on domain.

◆ giveDofManDofIDMask()

void oofem::IntElPoint::giveDofManDofIDMask	(	int	inode,

overridevirtual

Returns dofmanager dof mask for node. This mask defines the dofs which are used by element in node. Mask influences the code number ordering for particular node. Code numbers are ordered according to node order and dofs belonging to particular node are ordered according to this mask. If element requests dofs using node mask which are not in node then error is generated. This masking allows node to be shared by different elements with different dofs in same node. Elements local code numbers are extracted from node using this mask. Must be defined by particular element.

Parameters
