Detailed Description

template<template< typename P > typename T, class... Patches>
class MultipatchField< T, Patches >

A class to store field objects on patches.

On a multipatch domain when we have objects and types defined on different patches, e.g. fields. They can be stored in this class and then be accessed by the patch they are defined on.

Template Parameters

T	The type of the fields/derivative fields/vector fields that are stored on the given patches.
Patches	The patches of the objects in the same order of the patches that the given objects are defined on.

Warning: The objects have to be defined on different patches. Otherwise retrieving them by their patch is ill-defined.

Constructor & Destructor Documentation

◆ MultipatchField() [1/4]

template<template< typename P > typename T, class... Patches>

KOKKOS_FUNCTION MultipatchField< T, Patches >::MultipatchField ( T< Patches >... args )

inlineexplicit

Instantiate the MultipatchField class from an arbitrary number of objects.

Parameters

args	The objects to be stored in the class.

◆ MultipatchField() [2/4]

template<template< typename P > typename T, class... Patches>

template<class MultipatchObj , std::enable_if_t<!is_mem_type_v< MultipatchObj >, bool > = true>

KOKKOS_FUNCTION MultipatchField< T, Patches >::MultipatchField ( MultipatchObj & other )

inline

Create a MultipatchField class by copying an instance of another compatible MultipatchField.

A compatible MultipatchField is one which uses all the patches used by this class. The object being copied may include more patches than this MultipatchField. Further the original MultipatchField must store objects of the correct type (the type template may be different but return the same type depending on how it is designed).

This function is not explicit as it is helpful to be able to change between equivalent multipatch definitions if the internal type is the same but the definition comes from different locations in the code.

Parameters

other The equivalent MultipatchField being copied.

◆ MultipatchField() [3/4]

template<template< typename P > typename T, class... Patches>

template<class MultipatchObj , std::enable_if_t< is_mem_type_v< MultipatchObj >, bool > = true>

MultipatchField< T, Patches >::MultipatchField ( MultipatchObj & other )

inlineexplicit

Create a MultipatchField class from a compatible MultipatchFieldMem.

A compatible MultipatchField is one which uses all the patches used by this class. The object being copied may include more patches than this MultipatchField. Further the original MultipatchField must store objects of the correct type.

Parameters

other The MultipatchFieldMem being accessed.

◆ MultipatchField() [4/4]

template<template< typename P > typename T, class... Patches>

template<template< typename P > typename OT, class... OPatches>

MultipatchField< T, Patches >::MultipatchField ( MultipatchField< OT, OPatches... > && other )

inline

Create a MultipatchField class from an r-value (temporary) instance of another MultipatchField which uses the same type for the internal tuple.

Parameters

other The equivalent MultipatchField being copied.

Member Function Documentation

◆ get()

template<template< typename P > typename T, class... Patches>

template<class Patch >

KOKKOS_FUNCTION auto MultipatchField< T, Patches >::get ( ) const

inline

Retrieve an object from the patch that it is defined on.

Template Parameters

Patch The patch of the object to be returned.

Returns: The object on the given patch.

◆ idx_range()

template<template< typename P > typename T, class... Patches>

auto MultipatchField< T, Patches >::idx_range ( ) const

inline

Get a MultipatchType containing the index ranges on which the fields are defined.

Returns: The set of index ranges on which the set of fields stored in this class are defined.

◆ get_field()

template<template< typename P > typename T, class... Patches>

KOKKOS_FUNCTION auto MultipatchField< T, Patches >::get_field ( )

inline

Get a MultipatchField containing modifiable fields.

Returns: A set of modifiable fields providing access to the fields stored in this class.

◆ span_view()

template<template< typename P > typename T, class... Patches>

KOKKOS_FUNCTION auto MultipatchField< T, Patches >::span_view ( )

inline

Get a MultipatchField containing modifiable fields.

This function matches the DDC name to allow the global get_const_field to be defined.

Returns: A set of modifiable fields providing access to the fields stored in this class.

◆ get_const_field()

template<template< typename P > typename T, class... Patches>

KOKKOS_FUNCTION auto MultipatchField< T, Patches >::get_const_field ( ) const

inline

Returns: A set of constant fields providing access to the fields stored in this class.

◆ span_cview()

template<template< typename P > typename T, class... Patches>

KOKKOS_FUNCTION auto MultipatchField< T, Patches >::span_cview ( )

inline

Get a MultipatchField containing constant fields so the values cannot be modified.

This function matches the DDC name to allow the global get_const_field to be defined.

Returns: A set of constant fields providing access to the fields stored in this class.
