Detailed Description

template<class FunctionType>
class Dune::ACFem::UnaryGridFunctionExpression< InvertOperation, FunctionType >

For the sake of BoundarySupportedFunction we need to specialize the InvertOperation.

The InvertOperation produce UNDEFINED RESULTS outside the support in order to be mathematically correct. Hence the inverse of a BoundarySupportedFunction has always support on the entire boundary and will produce HUGE_VAL results outside the support of the original function. It must be this way.

indicator()

template<class FunctionType >

IndicatorType Dune::ACFem::UnaryGridFunctionExpression< InvertOperation, FunctionType >::indicator ( ) const

inline

Resulting Boundary indicator type.

name()

const std::string& Dune::ACFem::GridFunctionExpression< FunctionType::FunctionSpaceType , UnaryGridFunctionExpression< InvertOperation, FunctionType > , ExpressionTemplate >::name ( ) const

inlineinherited

Return a descriptive name for the function.

If set by setName(), return that user-supplied name. Otherwise return a (lengthy) auto-generated name describing the underlying algebraic expression.

setName()

void Dune::ACFem::GridFunctionExpression< FunctionType::FunctionSpaceType , UnaryGridFunctionExpression< InvertOperation, FunctionType > , ExpressionTemplate >::setName ( const std::string &  newName )

inlineinherited

Supply a descriptive name for the function.

This name will also be stored in the VTK files. It should be a "valid variable name".
