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.

Definition at line 48 of file StokesFlowProblemDefinition.hpp.

Constructor & Destructor Documentation

◆ StokesFlowProblemDefinition()

Constructor (initialises viscosity to -1 so can check if it is unset

Parameters
rMeshQuadratic mesh

Definition at line 59 of file StokesFlowProblemDefinition.hpp.

◆ ~StokesFlowProblemDefinition()

template<unsigned DIM>
virtual StokesFlowProblemDefinition< DIM >::~StokesFlowProblemDefinition ( )

Member Function Documentation

◆ GetViscosity()

template<unsigned DIM>
double StokesFlowProblemDefinition< DIM >::GetViscosity ( )
inline
Returns
the viscosity. Exception thrown if this hasn't been set yet.

Definition at line 83 of file StokesFlowProblemDefinition.hpp.

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

◆ SetPrescribedFlowNodes()

template<unsigned DIM>
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
rPrescribedFlowNodesvector of node indices.
rPrescribedFlowvector of prescribed flow values for these nodes.

Definition at line 112 of file StokesFlowProblemDefinition.hpp.

References ContinuumMechanicsProblemDefinition< DIM >::mDirichletNodes, and ContinuumMechanicsProblemDefinition< DIM >::mDirichletNodeValues.

◆ SetViscosity()

template<unsigned DIM>
void StokesFlowProblemDefinition< DIM >::SetViscosity ( double  mu)
inline

Set the viscosity

Parameters
muviscosity

Definition at line 74 of file StokesFlowProblemDefinition.hpp.

References StokesFlowProblemDefinition< DIM >::mMu.

◆ SetZeroFlowNodes()

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
rZeroFlowNodesNodes on which to apply the boundary conditions

Definition at line 97 of file StokesFlowProblemDefinition.hpp.

References ContinuumMechanicsProblemDefinition< DIM >::SetZeroDirichletNodes().

◆ Validate()

template<unsigned DIM>
virtual void StokesFlowProblemDefinition< DIM >::Validate ( )
inlinevirtual

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 >.

Definition at line 124 of file StokesFlowProblemDefinition.hpp.

References ContinuumMechanicsProblemDefinition< DIM >::Validate().
