Detailed Description

Container for various descendants of FieldCommonBase.

Provides various collective operations. Typical usage:

class EqData : public FieldSet { EqData() { *this += scalar_field .name("scalar_field") .description("Some description for input and output documentation.") .input_default("{0.0}") .units("m"); *this += vector_field .name("vector_field") .description("Some description for input and output documentation.") .units("m"); }

Field<3, FieldValue<3>::Scalar> scalar_field; Field<3, FieldValue<3>::Vector> vector_field; };

This way the fields are destructed just before their pointers stored in the FieldSet.

TODO: Some set_XY functions set also to the fields added to the FieldSet in future. This behavior should be removed, since it is misleading in combination with mask subsets. If one set something to mask subset, it does not influence fields added to the original field set even if they match the mask of the subset.

Member Function Documentation

FieldCommon & FieldSet::add_field	(	FieldCommon *	field,
		const string &	name,
		const string &	desc,
		const string &	d_val = `""`
	)

OBSOLETE

Adds given field into list of fields for group operations on fields. Parameters are: field pointer, name of the key in the input, desc - description of the key, and optional parameter d_val with default value. This method is rather called through the macro ADD_FIELD

bool FieldSet::changed ( ) const

Collective interface to FieldCommonBase::set_mesh().

Definition at line 120 of file field_set.cc.

Here is the caller graph for this function:

FieldSet::DECLARE_EXCEPTION	(	ExcUnknownField	,
		<< "Field set has no field with name: "<< FieldCommon::EI_Field::qval
	)

FieldCommon * FieldSet::field ( const std::string & field_name ) const

Return pointer to the field given by name field_name. Return nullptr if not found.

Definition at line 102 of file field_set.cc.

Here is the caller graph for this function:

void FieldSet::flags_add ( FieldFlag::Flags::Mask mask )

inline

Collective interface to FieldCommonBase::flags_add().

Parameters

mask	mask to set for all fields in the field set.

Definition at line 179 of file field_set.hh.

bool FieldSet::is_constant ( Region reg ) const

Collective interface to FieldCommonBase::set_mesh().

Definition at line 128 of file field_set.cc.

Here is the caller graph for this function:

Input::Type::Record FieldSet::make_field_descriptor_type ( const std::string & equation_name ) const

Add an existing Field to the list. It stores just pointer to the field. Be careful to not destroy passed Field before the FieldSet.

Using operator allows elegant setting and adding of a field to the field set:

        Field<...> init_quantity; // member of a FieldSet descendant
  
        field_set +=
            some_field
            .disable_where(type, {dirichlet, neumann}) // this must come first since it is not member of FieldCommonBase
            .name("init_temperature")
            .description("Initial temperature");
  
  /
FieldSet &operator +=(FieldCommon &add_field);
/**
  * Add other FieldSet to current one.
  */
FieldSet &operator +=(const FieldSet &other);
/**
  * Make new FieldSet as a subset of *this. The new FieldSet contains fields with names given by the @p names parameter.
  */
FieldSet subset(std::vector<std::string> names) const;
/**
 * Make new FieldSet as a subset of *this.
 * The new FieldSet contains all fields that match given @p mask.
 */

/**

inline unsigned int size() const {
    return field_list.size();
}
/**
  * Returns input type for a field descriptor, that can contain any of the fields in the set.
  * Typical usage is from derived class, where we add fields in the constructor and make auxiliary temporary instance
  * to get the record of the field descriptor. Simplest example:
  
  * @code
  * class EqData : public FieldSet {
  * public:
  *         // fields
  *         Field<..> field_a;
  *         Field<..> field_b
  *         EqData() {
  *             add(field_a);
  *             add(field_b);
  *         }
  * }
  
  * Input::Type::Record SomEquation::input_type=
  *         Record("SomeEquation","equation's description")
  *         .declare_key("data",Input::Type::Array(EqData().make_field_descriptor_type()),"List of field descriptors.");
  *

Input::Type::Selection FieldSet::make_output_field_selection	(	const string &	name,
		const string &	desc = `""`
	)

Make Selection with strings for all field names in the FieldSet.

Definition at line 69 of file field_set.cc.

Here is the caller graph for this function:

void FieldSet::mark_input_times ( TimeMark::Type mark_type )

inline

Collective interface to FieldCommonBase::mar_input_times().

Definition at line 201 of file field_set.hh.

Here is the caller graph for this function:

FieldCommon & FieldSet::operator[] ( const std::string & field_name ) const

Returns reference to the field given by field_name. Throws if the field with given name is not found.

Definition at line 110 of file field_set.cc.

void FieldSet::output ( OutputTime * stream )

Collective interface to FieldCommonBase::output().

Definition at line 136 of file field_set.cc.

Here is the caller graph for this function:

void FieldSet::output_type ( OutputTime::DiscreteSpace rt )

inline

Collective interface to FieldCommonBase::output_type().

Parameters

rt	Discrete function space (element, node or corner data).

Definition at line 194 of file field_set.hh.

Here is the caller graph for this function:

void FieldSet::set_field	(	const std::string &	dest_field_name,
		FieldCommon &	source
	)

Use FieldCommonBase::copy_from() to set field of the field set given by the first parameter dest_field_name. The source field is given as the second parameter source. The field copies share the same input descriptor list and the same instances of FieldBase classes but each copy can be set to different time and different limit side.

See FieldCommonBase::copy_from documentation for details.

Here is the caller graph for this function:

void FieldSet::set_input_list ( Input::Array input_list )

Here is the caller graph for this function:

void FieldSet::set_n_components ( unsigned int n_comp )

inline

Collective interface to FieldCommonBase::set_n_components(). It is safe to call this for field sets containing also fields with return value other then variable vector as long as all variable vector fields should be set to the same number of components.

void FieldSet::set_time ( const TimeGovernor & time )
