class Dune::ACFem::ZeroGridFunction< FunctionSpace, GridPart >

A grid-function always returning 0.

Member Function Documentation

name()

template<class FunctionSpaceImp , class ExpressionImp , template< class > class ExpressionTag = ExpressionTemplate>

const std::string& Dune::ACFem::GridFunctionExpression< FunctionSpaceImp, ExpressionImp, ExpressionTag >::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.

References Dune::ACFem::ExpressionTemplate< ExpressionImp >::expression().

setName()

template<class FunctionSpaceImp , class ExpressionImp , template< class > class ExpressionTag = ExpressionTemplate>

void Dune::ACFem::GridFunctionExpression< FunctionSpaceImp, ExpressionImp, ExpressionTag >::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".
