Detailed Description

Class implementing node connected to other node (master) using rigid arm in finite element mesh. The Rigid arm node supports not only slave dofs mapped to master throug rigid arm connection but also some dofs can be primary dofs (specified by masterDofMask attribute) The primary DOFs can have their own BCs, ICs.

The introduction of rigid arm connected nodes allows to avoid very stiff elements used for modeling the rigid-arm connection. The rigid arm node maps its dofs to master dofs using simple transformations (small rotations are assumed). Therefore, the contribution to rigid arm node are localized directly to master related equations. The rigid arm node can not have its own boundary or initial conditions on linked DOFs, they are determined completely from master dof conditions.

Updated by bp: The local coordinate system in slave is supported in current implementation, the coordinate system in master and slave can be different. If no lcs is set, global one is assumed.the global cs applies.

On the other hand, rigid arm node can be loaded independently of master. The transformation for DOFs and load is not orthogonal - the inverse transformation can not be constructed by transposition. Because of time consuming inversion, methods can generally compute both transformations for dofs as well as loads.

◆ checkConsistency()

int oofem::RigidArmNode::checkConsistency ( void )

overridevirtual

Allows programmer to test some internal data, before computation begins. For example, one may use this function, to ensure that element has material with required capabilities is assigned to element. This must be done after all mesh components are instanciated.

Returns: Nonzero if receiver is consistent.

◆ updateLocalNumbering()

void oofem::RigidArmNode::updateLocalNumbering ( EntityRenumberingFunctor & f )

overridevirtual

Local renumbering support. For some tasks (parallel load balancing, for example) it is necessary to renumber the entities. The various FEM components (such as nodes or elements) typically contain links to other entities in terms of their local numbers, etc. This service allows to update these relations to reflect updated numbering. The renumbering function is passed, which is supposed to return an updated number of specified entity type based on old number.
