Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM, unsigned PROBLEM_DIM>
class AbstractAssembler< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >

AbstractAssembler

Base class from which all solvers for linear and nonlinear PDEs inherit. Templated over the PROBLEM_DIM so also handles problems with more than one unknown variable (ie those of the form u_xx + v = 0, v_xx + 2u = 1, where PROBLEM_DIM is equal to 2)

It defines a common interface for AssembleSystem, AssembleOnElement and AssembleOnSurfaceElement. Each of these work for any PROBLEM_DIM>=1. Each of these methods work in both the dynamic case (when there is a current solution available) and the static case. The same code is used for the nonlinear and linear cases. Default code is defined in AbstractStaticAssembler

user calls:

Solve(). In the linear case Solve() calls AssembleSystem() directly, in the nonlinear case Solve() calls the PETSc nonlinear solver which then calls AssembleResidual or AssembleJacobian, both of which call AssembleSystem():

AssembleSystem(). (implemented in AbstractStaticAssembler, loops over elements and adds to the linear system or residual vector or jacobian matrix) AssembleSystem() calls:

AssembleOnElement() and AssembleOnSurfaceElement(). (implemented in AbstractStaticAssembler. These loop over gauss points and create the element stiffness matrix and vector in the linear case ). They call:

ComputeMatrixTerm(), ComputeVectorTerm(), ComputeVectorSurfaceTerm() (implemented in the concrete assembler class (eg SimpleDg0ParabolicAssembler), which tells this assembler exactly what function of bases, position, pde constants etc to add to the element stiffness matrix/vector).

void AbstractAssembler< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::ApplyNeummanBoundaryConditions ( ) [inline, protected]

Apply Neumann boundary conditions to the RHS vector by looping over surface elements (though actually looping over the boundary condition objects).

Note for PROBLEM_DIM>1. We assume that if an element has a boundary condition on any unknown there is a boundary condition on unknown 0. This can be so for any problem by adding zero constant conditions where required although this is a bit inefficient. Proper solution involves changing BCC to have a map of arrays boundary conditions rather than an array of maps.

AssembleSystem - the major method for all assemblers

Assemble the linear system for a linear PDE, or the residual or Jacobian for nonlinear PDEs. Loops over each element (and each each surface element if there are non-zero Neumann boundary conditions), calls AssembleOnElement() and adds the contribution to the linear system.

Takes in current solution and time if necessary but only used if the problem is a dynamic one. This method uses PROBLEM_DIM and can assemble linear systems for any number of unknown variables.

Parameters:

	assembleVector	Whether to assemble the RHS vector of the linear system (i.e. the residual vector for nonlinear problems).
	assembleMatrix	Whether to assemble the LHS matrix of the linear system (i.e. the jacobian matrix for nonlinear problems).
	currentSolutionOrGuess	The current solution in a linear dynamic problem, or the current guess in a nonlinear problem. Should be NULL for linear static problems. Defaults to NULL.
	currentTime	The current time for dynamic problems. Not used in static problems. Defaults to 0.0.

	)			`[protected, pure virtual]`

This method returns the matrix to be added to element stiffness matrix for a given gauss point. The arguments are the bases, bases gradients, x and current solution computed at the Gauss point. The returned matrix will be multiplied by the gauss weight and jacobian determinent and added to the element stiffness matrix (see AssembleOnElement()).

--This method has to be implemented in the concrete class--

NOTE: for linear problems rGradU is NOT set up correctly because it should not be needed

Parameters:

	rPhi	The basis functions, rPhi(i) = phi_i, i=1..numBases.
	rGradPhi	Basis gradients, rGradPhi(i,j) = d(phi_j)/d(X_i).
	rX	The point in space.
