Detailed Description

template<class FactorFunction, class OperandType>
class Dune::ACFem::BinaryOperatorPartsExpression< MultiplyOperation, FactorFunction, OperandType >

Multiplication with grid-functions.

The implementation makes sure that the fluxDivergence() method correctly takes the derivatives of the factor functions into account.

Note: We specialize the expression-class explicitly because the recurse to the static methods of the expression-operations class just does not make this stuff less complicated. Instead we define the s-multiplication expression explicitly here.; We only define the class for multiplication with scalars from the left and define multiplication and division from the right via the operator functions (given that multiplication is commutative, which is not correct for complicated expressions when taking round-off errors into account.

Bug:: Due to a bug in the OperatorParts the localFactor_ has to be tagged as "mutable".
