ApplyConstraints()

void Kratos::ConstraintUtilities::ApplyConstraints

(

ModelPart &

rModelPart

)

This method resets the values of the slave dofs.

Parameters

rModelPart

The model of the problem to solve

ComputeActiveDofs()

void Kratos::ConstraintUtilities::ComputeActiveDofs	(	ModelPart &	rModelPart,
		std::vector< int > &	rActiveDofs,
		const ModelPart::DofsArrayType &	rDofSet
	)

This method computes the active dofs.

Parameters

rModelPart	Reference to the ModelPart containing the problem
rActiveDofs	Vector containing the active dofs
rDofSet	The whole set of dofs

DistributedComputeActiveDofs()

void Kratos::ConstraintUtilities::DistributedComputeActiveDofs	(	ModelPart &	rModelPart,
		std::vector< int > &	rActiveDofs,
		const ModelPart::DofsArrayType &	rDofSet,
		const std::size_t	InitialDofId
	)

This method computes the active dofs.

Parameters

rModelPart	Reference to the ModelPart containing the problem
rActiveDofs	Vector containing the active dofs
rDofSet	The whole set of dofs

PreComputeExplicitConstraintConstribution()

void Kratos::ConstraintUtilities::PreComputeExplicitConstraintConstribution	(	ModelPart &	rModelPart,
		const std::vector< std::string > &	rDofVariableNames,
		const std::vector< std::string > &	rResidualDofVariableNames
	)

This method precomputes the contribution of the explicit MPC over nodal residual forces.

Parameters

rModelPart	The model of the problem to solve
rDofVariableNames	The name of the Dof variables to check
rResidualDofVariableNames	The name name of the corresponding residual variables

PreComputeExplicitConstraintMassAndInertia()

void Kratos::ConstraintUtilities::PreComputeExplicitConstraintMassAndInertia	(	ModelPart &	rModelPart,
		const std::string &	DofDisplacementVariableName = "DISPLACEMENT",
		const std::string &	MassVariableName = "NODAL_MASS",
		const std::string &	DofRotationVariableName = "ROTATION",
		const std::string &	InertiaVariableName = "NODAL_INERTIA_TENSOR"
	)

This method precomputes the contribution of the explicit MPC over nodal masses and inertias.

Todo:

The inertia must be computed using the Steiner theorem https://en.wikipedia.org/wiki/Parallel_axis_theorem

Parameters

rModelPart	The model of the problem to solve
DofDisplacementVariableName	The name of the Dof variables to check
MassVariableName	The name of the variable of the nodal mass
DofRotationVariableName	The name of the rotational variable name
InertiaVariableName	The inertia variable to be considered

ResetSlaveDofs()

void Kratos::ConstraintUtilities::ResetSlaveDofs

(

ModelPart &

rModelPart

)

This method resets the values of the slave dofs.

Parameters
