Detailed Description

class AbstractFunctionalCalculator< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >
This is an abstract class for computing user-defined integral-based functionals of a solution on the mesh. The user needs to define GetIntegrand() in the concrete class, and this class can then be used to compute the integral of f(x,u,grad_u) over the mesh, where x is position, u is the solution at x (possibly with multiple components, for which PROBLEM_DIM>1), grad_u the gradient of u and f the integrand as defined in the concrete class.Note linear basis functions and 2 quad points per dimension are currently hardcoded.

Get the integrand. Must be defined by the user.
- Parameters:
-
rX The point in space rU The unknown as a vector, u(i) = u_i rGradU The gradient of the unknown as a matrix, rGradU(i,j) = d(u_i)/d(X_j)

| double AbstractFunctionalCalculator< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::CalculateOnElement | ( | Element< ELEMENT_DIM, SPACE_DIM > & | rElement | ) | [inline, private] |
Compute the contribution to the integral from one element.
- Parameters:
-
rElement The element
NOTE: This assumes that the Jacobian is constant on an element, ie no curvilinear bases were used for position
- Todo:
- Check if we are using a mesh with cached Jacobians, if so, get it from the mesh rather than calling the calculate method.
