void fill_in_contribution_to_jacobian (Vector< double > &residuals, DenseMatrix< double > &jacobian)

unsigned ndof_types () const
 The number of "DOF types" that degrees of freedom in this element are sub-divided into - it's set to Dof_number_for_unknown+1 because it's expected this element is added to a fluid mesh containing navier stokes elements. More...
 
unsigned & dof_number_for_unknown ()
 Function to set / get the nodal value of the "DOF type" to which the degree of freedom in this element (the pressure that enforces the required volume flux!) is added to. This should be set to the Navier-Stokes pressure DOF type (usually the dimension of the problem, for example, in 3D, the DOF types for single-physics Navier-Stokes elements are usually labelled 0, 1, 2, 3 for u, v and w velocities and pressure respectively. It is important to note that this is dimension dependent, so should not be hard coded in!! In particularly, this should not simply be set to the dimension of the problem if there is further splitting of the velocity DOF types) if this element is added to a fluid mesh containing Navier-Stokes elements. More...

The single degree of freedom is given the DOF type number of Dof_number_for_unknown since it's expected this unknown is added to the Navier-Stokes pressure DOF block (it is also assumed that the user has set the Dof_number_for_unknown variable to the velocity DOF type using the function dof_number_for_unknown()).

Detailed Description

A class for an element that controls the net fluid flux across a boundary by the imposition of an unknown applied pressure to the Navier-Stokes equations. This element is used with a mesh of NavierStokesFluxControlElement elements which are attached to the boundary. Note: fill_in_contribution_to_jacobian() does not calculate Jacobian contributions for this element as they are calculated by NavierStokesFluxControlElement::fill_in_contribution_to_jacobian(...)

Function to set / get the nodal value of the "DOF type" to which the degree of freedom in this element (the pressure that enforces the required volume flux!) is added to. This should be set to the Navier-Stokes pressure DOF type (usually the dimension of the problem, for example, in 3D, the DOF types for single-physics Navier-Stokes elements are usually labelled 0, 1, 2, 3 for u, v and w velocities and pressure respectively. It is important to note that this is dimension dependent, so should not be hard coded in!! In particularly, this should not simply be set to the dimension of the problem if there is further splitting of the velocity DOF types) if this element is added to a fluid mesh containing Navier-Stokes elements.

unsigned oomph::NetFluxControlElement::Dof_number_for_unknown
private

The id number of the "DOF type" to which the degree of freedom in this element is added to. This should be set to the number id of the Navier-Stokes pressure DOF block (which is dimension dependent!) if this element is added to a fluid mesh containing navier stokes elements.
