Extension of the previous method. Return possible values from the enum FieldResult, see description there. The initial state is field_none, if the field is correctly set on all regions of the region_set given as parameter we return state field_other or even more particular result.

Special field values spatially constant.

We return value result_none, if the field is not initialized on the region of the given element accessor elm. Other possible results are: result_zeros, result_eye, result_ones, result_constant, result_other see FieldResult for explanation.

FieldCommon& FieldCommon::input_default ( const string & input_default )

inline

Set default value for the field's key from which the default constant valued field will be constructed.

During the first call of the set_time method, we check that the field is defined on all regions. On regions where it is not set yet, we use given dflt string to get particular instance of FieldBase<> (see check_initialized_region_fields_). The default string is interpreted in the same way as if it appears in the input file as the value of the field. In particular it can be whole record with TYPE of the field etc. Most common choice is however mere constant.

Here is the caller graph for this function:

virtual bool FieldCommon::is_constant ( Region reg )

pure virtual

If the field on given region reg exists and is of type FieldConstant<...> the method method returns true otherwise it returns false. Then one can call ElementAccessor<spacedim>(mesh(), reg ) to construct an ElementAccessor elm pointing to "virtual" element on which Field::value returns constant value. Unlike the Field<>::field_result method, this one provides no value, so it have common header (arguments, return type) and could be part of FieldCommon and FieldSet which is useful in some applications.

TODO:Current implementation use virtual functions and can be prohibitively slow if called for every element. If this becomes necessary it is possible to incorporate such test into set_time method and in this method just return precomputed result.

const unsigned int FieldCommon::history_length_limit_ =3

staticprotected

Maximum number of FieldBase objects we store per one region.

Definition at line 636 of file field_common.hh.

bool FieldCommon::is_jump_time_

protected

Set to true by the set_time method the field algorithm change on any region. Accessible through the is_jump_time method.

Definition at line 615 of file field_common.hh.

LimitSide FieldCommon::last_limit_side_ = LimitSide::left

protected

Definition at line 609 of file field_common.hh.

double FieldCommon::last_time_ = -numeric_limits<double>::infinity()

protected

Last set time. Can be different for different field copies. Store also time limit, since the field may be discontinuous.

std::vector< FieldCommon::MessageData > FieldCommon::messages_data_ = std::vector<FieldCommon::MessageData>()

staticprotected

Vector of data of initialization messages.

Definition at line 642 of file field_common.hh.

bool FieldCommon::multifield_

protected

Flag determining if object is Multifield or Field. TODO: temporary solution, goal is to make these two classes to behave similarly

Definition at line 631 of file field_common.hh.

std::string FieldCommon::name_

protected

Name that identifies the field in the field_set. By default this is same as shared_->input_name_.

Definition at line 581 of file field_common.hh.

TimeStatus FieldCommon::set_time_result_

protected

Status of history.

Definition at line 602 of file field_common.hh.

std::shared_ptr<SharedData> FieldCommon::shared_

protected

Data shared among copies of the same input field.

Definition at line 586 of file field_common.hh.

OutputTime::DiscreteSpace FieldCommon::type_of_output_data_ = OutputTime::ELEM_DATA

protected
