Detailed Description

template<unsigned DIM>
class StokesFlowProblemDefinition< DIM >

Class for defining everything needed for a solving the Stokes' Flow equations. This class mainly allows for the setting of the viscosity. It inherits from a class which allows for the setting of body force, density and various types of boundary condition.

double StokesFlowProblemDefinition< DIM >::GetViscosity

(

)

[inline]

Get the viscosity. Exception thrown if this hasn't been set yet.

Definition at line 76 of file StokesFlowProblemDefinition.hpp.

References EXCEPTION, and StokesFlowProblemDefinition< DIM >::mMu.

void StokesFlowProblemDefinition< DIM >::SetPrescribedFlowNodes	(	std::vector< unsigned > &	rPrescribedFlowNodes,
		std::vector< c_vector< double, DIM > > &	rPrescribedFlow
	)			[inline]

Set Dirichlet boundary conditions: provide a set of nodes and the prescribed flow on these nodes.

If you only want to set one component of the flow for the node rPrescribedFlowNodes[i], set the other components of rPrescribedFlow[i] to be StokesFlowProblemDefinition::FREE.

Parameters:

	rPrescribedFlowNodes	vector of node indices.
	rPrescribedFlow	vector of prescribed flow values for these nodes.

void StokesFlowProblemDefinition< DIM >::SetViscosity

(

double

mu

)

[inline]

Set the viscosity

Parameters:

mu

viscosity

template<unsigned DIM>

void StokesFlowProblemDefinition< DIM >::SetZeroFlowNodes

(

std::vector< unsigned > &

rZeroFlowNodes

)

[inline]

Set nodes on which to apply the boundary condition (u,v,w)=0, ie flow = 0 in all components. Just calls SetZeroDirichletNodes() on the parent class.

Parameters:

rZeroFlowNodes

Nodes on which to apply the boundary conditions

Definition at line 90 of file StokesFlowProblemDefinition.hpp.

References ContinuumMechanicsProblemDefinition< DIM >::SetZeroDirichletNodes().

template<unsigned DIM>

virtual void StokesFlowProblemDefinition< DIM >::Validate

(

)

[inline, virtual]

Check all variables are set appropriately. Exceptions are thrown if any are not. Derived classes can override but should call this version as well.

Reimplemented from ContinuumMechanicsProblemDefinition< DIM >.
