Bases: proteus.TransportCoefficients.TC_base

Set the number of components (equations) of the PDE and initialize the dicitionaries describing the form of the coefficients. Strings naming each component (used for viewing and archiving) and a structure defining the sparsity pattern of diffusion tensors may also be provided.

initialize()

initializeMesh(mesh)

Give the TC object access to the mesh for any mesh-dependent information.

attachModels(modelList)

Give the TC object access to other models in a loosely coupled split operator formulation (e.g. a transport equation for concentration might get velocity from a flow equation)

initializeElementQuadrature(t, cq)

Give the TC object access to the element quadrature storage

initializeElementBoundaryQuadrature(t, cebq, cebq_global)

Give the TC object access to the element boundary quadrature storage

initializeGlobalExteriorElementBoundaryQuadrature(t, cebqe)

Give the TC object access to the exterior element boundary quadrature storage

preStep(t, firstStep=False)

Give the TC object an opportunity to modify itself before the time step.

postStep(t, firstStep=False)

Give the TC object an opportunity to modify itself after the time step.

updateToMovingDomain(t, c)

evaluate(t, c)

Evaluate the coefficients at a given time, t, using the coefficient storage passed in as the dictionary c.

Bases: proteus.Transport.OneLevelTransport

Allocate storage and initialize some variables.

Parameters

• uDict (dict) – Dictionary of proteus.FemTools.FiniteElementFunction objects.

• phiDict (dict) – Dictionary of proteus.FemTools.FiniteElementFunction objects.

• testSpaceDict (dict) – Dictionary of FiniteElementSpace objects

• dofBoundaryConditionsDict (dict) – Dictionary of DOFBoundaryConditions objects for the Dirichlet conditions.

• coefficients (proteus.TransportCoefficients.TC_base) – Problem’s Transport Coefficients class.

• elementQuadratureDict (dict) – Dictionary of dictionaries of quadrature rules for each element integral in each component equation.

• elementBoundaryQuadratureDict (dict) – Dictionary of dictionaries of quadrature rules for each element boundary integral in each component equation

• stabilization (bool) –

• shockCapturing (bool) –

• numericalFlux (bool) –

• bdyNullSpace (bool) – Indicates whether the boundary conditions create a global null space.

Notes

The constructor sets the input arguments, calculates dimensions, and allocates storage. The meanings of variable suffixes are

• global – per physical domain

• element – per element

• elementBoundary – per element boundary

The prefix n means ‘number of’.

Storage is divided into quantities required at different sets of points or geometric entities. Each type of storage has a dictionary for all the quantities of that type. The names and dimensions of the storage dictionaries are

• e – at element

• q – at element quadrature, unique to elements

• ebq – at element boundary quadrature, unique to elements

• ebq_global – at element boundary quadrature, unique to element boundary

• ebqe – at element boundary quadrature, unique to global, exterior element boundary

• phi_ip – at the generalized interpolation points required to build a nonlinear phi
