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.

	)

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.
