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

Member Function Documentation

template<int spacedim, class Value >
arma::vec FieldFormula< spacedim, Value >::eval_depth_var ( const Point p)
inlineprivate

Evaluate depth variable if it is contained in formula.

Return arma vec of point coordinates extended by depth value (or zero if depth is not contained.

template<int spacedim, class Value >
void FieldFormula< spacedim, Value >::init_from_input ( const Input::Record rec,
const struct FieldAlgoBaseInitData init_data

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

TODO: make protected, should be called through function factory

Definition at line 85 of file field_formula.cc.

template<int spacedim, class Value >
void FieldFormula< spacedim, Value >::set_mesh ( const Mesh mesh,
bool  boundary_domain 
)
overridevirtual

Create SurfaceDepth object if surface region is set.

See also description of the FieldBase<...>::set_mesh.

Reimplemented from FieldAlgorithmBase< spacedim, Value >.

Definition at line 186 of file field_formula.cc.

template<int spacedim, class Value >
bool FieldFormula< spacedim, Value >::set_time ( const TimeStep time)
overridevirtual

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 95 of file field_formula.cc.

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 199 of file field_formula.cc.

template<int spacedim, class Value >
