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>::VectorFixed> 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.

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

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

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

Here is the caller graph for this function:

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

inline

Collective interface to FieldCommonBase::flags_add().

Parameters

bool FieldSet::is_constant ( Region reg ) const

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");

/**
  * 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.
  * The returned Record has name equation_name + "_Data".
  
  * 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("SomeEquation")),"List of field descriptors.");

void FieldSet::mark_input_times ( const TimeGovernor & tg )

inline

Collective interface to FieldCommonBase::mark_input_times().

Definition at line 208 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 140 of file field_set.cc.

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 201 of file field_set.hh.

Here is the caller graph for this function:

void FieldSet::set_components ( const std::vector< string > & names )

inline

Collective interface to FieldCommonBase::set_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.

Definition at line 167 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
	)

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