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.

Implements FieldCommon.

Definition at line 356 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 176 of file multi_field.impl.hh.

◆ DECLARE_INPUT_EXCEPTION()

template<int spacedim, class Value >

<< "Invalid size "<< EI_Size::val<< "of the MultiField< spacedim, Value > "<< EI_MultiFieldName::qval<< "  ,

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.
