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.

Constructor & Destructor Documentation

◆ FieldSet()

FieldSet::FieldSet ( )

Default constructor.

Definition at line 29 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 251 of file field_set.cc.

Here is the caller graph for this function:

bool FieldSet::changed ( ) const

Collective interface to FieldCommonBase::set_mesh().

Definition at line 196 of file field_set.cc.

◆ DECLARE_INPUT_EXCEPTION() [1/3]

FieldSet::DECLARE_INPUT_EXCEPTION	(	ExcFieldExists	,

FieldSet::DECLARE_INPUT_EXCEPTION	(	ExcFieldNotSet	,
		<< "Field "<< FieldCommon::EI_Field::qval<< " is not set. Please set key 'scalar_field'	,

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);

/**

  */
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

  *             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.");
