◆ get_input_type()

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 33 of file field_constant.cc.

◆ init_from_input()

template<int spacedim, class Value >

void FieldConstant< spacedim, Value >::init_from_input	(	const Input::Record &	rec,
		const struct FieldAlgoBaseInitData &	init_data
	)

overridevirtual

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 75 of file field_constant.cc.

◆ set_value()

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 66 of file field_constant.cc.

◆ value()

template<int spacedim, class Value >

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

overridevirtual

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

	)

overridevirtual

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