Detailed Description

template<int spacedim, class Value>
class MultiField< spacedim, Value >

Class for representation of a vector of fields of the same physical quantity.

When solving a system of same equations with the number of components given at runtime (as in the case of transport equation for runtime given number of substances) we need means how to work with the whole vector of fields at once. This is the aim of this class. It provides the interface given by the parent class FieldCommonBase, but principally it is just a vector of Field<Value,dim> objects. The sub-fields or components of a MultiField are independent objects, how ever the setters propagates the values from the MultiFields to the individual fields. The only exception is the set_name method which in conjunction with MultiField::set_subfield_names can set unique name to each component.

Template parameters are used for every subfield.

TODO:

Definition of MultiField must be in separate file. In other case source file field.cc is too big and compiler can throw compile error.

◆ cache_reallocate()

template<int spacedim, class Value >
void MultiField< spacedim, Value >::cache_reallocate ( const ElementCacheMap cache_map,
unsigned int  region_idx 
) const
overridevirtual

Implements FieldCommon::cache_reallocate.

Implements FieldCommon.

Definition at line 389 of file multi_field.impl.hh.

◆ cache_update()

template<int spacedim, class Value >
void MultiField< spacedim, Value >::cache_update ( ElementCacheMap cache_map,
unsigned int  region_patch_idx 
) const
overridevirtual

Implements FieldCommon::cache_update.

Implements FieldCommon.

Definition at line 396 of file multi_field.impl.hh.

◆ copy_from()

template<int spacedim, class Value >
void MultiField< spacedim, Value >::copy_from ( const FieldCommon other)
overridevirtual

Polymorphic copy. Check correct type, allows copy of MultiField or Field.

Implements FieldCommon.

Definition at line 177 of file multi_field.impl.hh.

◆ DECLARE_INPUT_EXCEPTION()

template<int spacedim, class Value >
MultiField< spacedim, Value >::DECLARE_INPUT_EXCEPTION ( Exc_InvalidMultiFieldSize  ,
<< "Invalid size "<< EI_Size::val<< "of the MultiField< spacedim, Value > "<< EI_MultiFieldName::qval<< "  ,
expected size:"<< EI_ExpectedSize::val   
)

auto MultiField< spacedim, Value >::disable_where ( const MultiField< spacedim, typename FieldValue< spacedim >::Enum > &  control_field,

) -> MultiField &

By this method you can allow that the field need not to be set on regions (and times) where the given control_field is FieldConstant and has value in given value_list. We check this in the set_time method. Through this mechanism we can switch of e.g. boundary data fields according to the type of the boundary condition.

overridevirtual

Returns input type of particular field instance, this is usually static member input_type of the corresponding FieldBase class ( with same template parameters), however, for fields returning "Enum" we have to create whole unique Input::Type hierarchy for every instance since every such field use different Selection for initialization, even if all returns just unsigned int.

Implements FieldCommon.

double  time,
std::vector< std::string >  region_set_names = {"ALL"} 
)

Assigns fields from field_vec to individual components and all regions in region sets given by region_set_names. Field is added to the history with given time and possibly used in the next call of the set_time method. Caller is responsible for correct construction of given field.

Use this method only if necessary.

)
overridevirtual

Returns vector of value in one given point on an element given by ElementAccessor elm. It returns reference to he actual value in order to avoid temporaries for vector and tensor values. Returns std::vector of vector values in several points at once. The base class implements trivial implementation using the value(,,) method. This is not optimal as it involves lot of virtual calls, but this overhead can be negligible for more complex fields as Python of Formula.

Definition at line 302 of file multi_field.impl.hh.

◆ set_mesh()

template<int spacedim, class Value >
void MultiField< spacedim, Value >::set_mesh ( const Mesh mesh)

)
overridevirtual

Abstract method to update field to the new time level. Implemented by in class template Field<...>.

Return true if the value of the field was changed on some region. The returned value is also stored in changed_during_set_time data member.

In first call initialize MultiField to the number of components given by the size of names and use this vector to name individual components. Should be called after the setters derived from FieldCommonBase.
