Constructor & Destructor Documentation

template<int spacedim, class Value >
FieldConstant< spacedim, Value >::FieldConstant ( unsigned int  n_comp = 0)

Default constructor, optionally we need number of components n_comp in the case of Vector valued fields.

Member Function Documentation

template<int spacedim, class Value >
void FieldConstant< spacedim, Value >::check_field_limits ( const Input::Record rec,
const struct FieldAlgoBaseInitData init_data 
)
protected

Compare field value with given minimal and maximal limits.

Here is the caller graph for this function:

template<int spacedim, class Value >
const Input::Type::Record & FieldConstant< spacedim, Value >::get_input_type ( )
static

Implementation.

Return Record for initialization of FieldConstant that is derived from Abstract given by a_type and the individual elements of the possible Value (vector, tensor) have Input::Type eit.

Definition at line 32 of file field_constant.cc.

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

This method initialize actual value of the field given from the given Input::Record rec.

Reimplemented from FieldAlgorithmBase< spacedim, Value >.

Reimplemented in FieldTimeFunction< spacedim, Value >.

Definition at line 72 of file field_constant.cc.

template<int spacedim, class Value >
FieldConstant< spacedim, Value > & FieldConstant< spacedim, Value >::set_value ( const typename Value::return_type &  val)

Smart setter from the given value to return.

Definition at line 63 of file field_constant.cc.

template<int spacedim, class Value >
Value::return_type const & FieldConstant< 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 115 of file field_constant.cc.

template<int spacedim, class Value >
void FieldConstant< 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.

Implements FieldAlgorithmBase< spacedim, Value >.
