		IntArray &	restrDofs,
		IntArray &	eqn,
		TimeStep *	tStep,

Builds the reaction force table. For each prescribed equation number it will find corresponding node and dof number. The entries in the restrDofMans, restrDofs, and eqn arrays are sorted with increasing dofman number and with increasing dof number as a second minor criterion.

Parameters

restrDofMans	Contains numbers of restrained Dofmanagers, with size equal to total number of prescribed equations.
restrDofs	Contains IDs of restrained Dofs, with size equal to total number of prescribed equations.
eqn	Contains the corresponding restrained equation numbers.
tStep	Time step.

◆ checkConsistency()

int oofem::StructuralEngngModel::checkConsistency ( )

overridevirtual

Allows programmer to test some receiver's internal data, before computation begins.

Returns: Nonzero if receiver check is o.k.

◆ computeExternalLoadReactionContribution()

void oofem::StructuralEngngModel::computeExternalLoadReactionContribution	(	FloatArray &	reactions,
		TimeStep *	tStep,
		int	di )

protectedvirtual

Computes the contribution external loading to reaction forces in given domain. Default implementations adds the contribution from computeElementLoadReactionContribution and computeElementLoadReactionContribution methods.

Parameters

reactions	Contains the computed contributions.
tStep	Solution step.
di	Domain number.

Reimplemented in oofem::NonLinearStatic, and oofem::StaticStructural.

Referenced by computeReaction().

◆ computeReaction()

void oofem::StructuralEngngModel::computeReaction	(	FloatArray &	answer,
		TimeStep *	tStep,
		int	di )

Computes reaction forces. The implementation assumes, that real stresses corresponding to reached state are already computed (uses giveInternalForcesVector structural element service with useUpdatedGpRecord = 1 parameter). To be safe, this method should be called after convergence has been reached, eq., after engngModel->updateYourself() has been called.

Parameters

answer	Reactions, the ordering of individual values follows numbering of prescribed equations.
tStep	Time step.
di	Domain number.

Todo: All engineering models should be using this (for consistency)

Todo: This method is overloaded in some functions, it needs to be generalized.

Computes and prints reaction forces, computed from nodal internal forces.
