Detailed Description

template<int spacedim, class Value>
class FieldFormula< spacedim, Value >

Class representing fields given by runtime parsed formulas.

Using library: http://warp.povusers.org/FunctionParser/

TODO: correct support for discrete functions (use integer parser), actually we just convert double to int

Here is the caller graph for this function:

template<int spacedim, class Value >

void FieldFormula< spacedim, Value >::init_from_input ( const Input::Record & rec )

virtual

Function can provide way to initialize itself from the input data.

TODO: make protected, should be called through function factory

Reimplemented from FieldAlgorithmBase< spacedim, Value >.

Definition at line 62 of file field_formula.impl.hh.

template<int spacedim, class Value >

bool FieldFormula< spacedim, Value >::set_time ( double time )

virtual

For time dependent formulas returns always true. For time independent formulas returns true only for the first time.

Reimplemented from FieldAlgorithmBase< spacedim, Value >.

Definition at line 70 of file field_formula.impl.hh.

template<int spacedim, class Value >

Value::return_type const & FieldFormula< spacedim, Value >::value	(	const Point &	p,
		const ElementAccessor< spacedim > &	elm
	)

virtual

Returns one value in one given point. ResultType can be used to avoid some costly calculation if the result is trivial.

Implements FieldAlgorithmBase< spacedim, Value >.

Definition at line 135 of file field_formula.impl.hh.

template<int spacedim, class Value >

void FieldFormula< spacedim, Value >::value_list	(	const std::vector< Point > &	point_list,
		const ElementAccessor< spacedim > &	elm,
		std::vector< typename Value::return_type > &	value_list
	)

virtual

Returns std::vector of scalar values in several points at once.
