DefaultLocalAssemblerForIntegralOperatorsOnSurfaces< BasisFunctionType, KernelType, ResultType, GeometryFactory >::CoordinateType Fiber::DefaultLocalAssemblerForIntegralOperatorsOnSurfaces< BasisFunctionType, KernelType, ResultType, GeometryFactory >::estimateRelativeScale ( CoordinateType minDist ) const

virtual

Estimate how fast the entries in the matrix of this operator decay with interelement distance.

This function should return a rough (!) estimate of the magnitude of the entries in the matrix of this operator associated with a pair of test and trial elements lying a distance minDist from each other, relative to the estimated magnitude of entries associated with coincident elements. If no good estimate can be given, the function can return 1.

Note: This function is called during ACA to detect block clusters on which the operator becomes very small and so can be safely approximated with 0.

Assemble local weak forms.

In this overload, a "column" of local weak forms is assembled. More specifically, on exit result is a vector of local weak forms corresponding to the following pairs of elements:

if callVariant is TEST_TRIAL, all pairs (elementA, elementB) for elementA in elementsA;
if callVariant is TRIAL_TEST, all pairs (elementB, elementA) for elementA in elementsA.

Unless localDofIndexB is set to ALL_DOFS, only entries corresponding to the (localDofIndexB)th local DOF on elementB are calculated.

If nominalDistance is nonnegative, it is taken as the distance between all element pairs for the purposes of selecting the quadrature method. Otherwise the interelement distance is calculated separately for each element pair.

virtual

Assemble local weak forms.

This overload constructs and assigns to the output parameter result the 2D array of local weak forms corresponding to all pairs (testElement, trialElement) with testElement in testElementIndices and trialElement in trialElementIndices.

This function should be used primarily for small blocks of elements lying close to each other.

If nominalDistance is nonnegative, it is taken as the distance between all element pairs for the purposes of selecting the quadrature method. Otherwise the interelement distance is calculated separately for each element pair.
