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.

Constructor & Destructor Documentation

◆ FieldSet()

FieldSet::FieldSet ( )

Default constructor.

Definition at line 28 of file field_set.cc.

Member Function Documentation

◆ add_coords_field()

void FieldSet::add_coords_field ( )

Add coords field (X_) and depth field to field_list.

We can't add this field automatically in constructor, because there is problem in equation where we add one FieldSet to other.

Definition at line 228 of file field_set.cc.

◆ cache_reallocate()

void FieldSet::cache_reallocate ( const ElementCacheMap cache_map,
FieldSet used_fieldset 
)
inline

Collective interface to FieldCommon::recache_allocate().

Definition at line 332 of file field_set.hh.

◆ cache_update()

void FieldSet::cache_update ( ElementCacheMap cache_map)

Collective interface to FieldCommon::cache_update().

Definition at line 194 of file field_set.cc.

◆ changed()

bool FieldSet::changed ( ) const

Collective interface to FieldCommonBase::set_mesh().

Definition at line 172 of file field_set.cc.

Here is the caller graph for this function:

◆ DECLARE_EXCEPTION()

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

◆ 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.

Definition at line 147 of file field_set.cc.

◆ fields_range()

Range< FieldListAccessor > FieldSet::fields_range ( ) const

Returns range of Fields held in field_list.

Definition at line 245 of file field_set.cc.

Here is the caller graph for this function:

◆ flags_add()

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

Collective interface to FieldCommonBase::flags_add().

Parameters
maskmask to set for all fields in the field set.

Definition at line 290 of file field_set.hh.

◆ is_constant()

bool FieldSet::is_constant ( Region  reg) const

Collective interface to FieldCommonBase::set_mesh().

Definition at line 180 of file field_set.cc.

Here is the caller graph for this function:

◆ is_jump_time()

bool FieldSet::is_jump_time ( ) const

Collective interface to FieldCommonBase::is_jump_time().

Definition at line 187 of file field_set.cc.

◆ make_field_descriptor_type()

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.
*/
FieldSet subset( FieldFlag::Flags::Mask mask) const;
/**
* Number of fields in the FieldSet.
*/
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.
* 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.");
*
