Grid

namespace Cubism::Grid

Namespace for grid data types composed of block data types.

template<typename T, size_t RANK, Cubism::EntityType Entity, typename State, typename Mesh>
struct BlockFieldAssembler
#include <BlockFieldAssembler.h>

Block field assembler for an externally allocated region of memory.

Template Parameters

  • T: Field data type

  • RANK: Tensor rank

  • Entity: Entity type

  • State: Field state type

  • Mesh: Mesh type of global and block meshes

template<typename T, typename Mesh, Cubism::EntityType Entity = Cubism::EntityType::Cell, size_t RANK = 0, typename UserState = Block::FieldState, template<typename> class Alloc = AlignedBlockAllocator>
class Cartesian
#include <Cartesian.h>

Cartesian block (tensor) field.

Cartesian topology composed of block Field.h for the specified entity type. As opposed to an individual block Field.h, this class manages a structure of arrays (SoA) memory layout for all the blocks in the Cartesian topology instead of just individual blocks. See the CartesianMPI.h grid section for a distributed variant of this class. The field state can be extended with the UserState extension. The UserState type must be trivially copyable.

Template Parameters

  • T: Field data type

  • Mesh: Mesh type to be associated with fields

  • Entity: Entity type

  • RANK: Rank of (tensor) fields

  • UserState: Type for field state user extension

  • Alloc: Allocator for field data

Subclassed by Cubism::Grid::CartesianMPI< T, Mesh, Entity, RANK, UserState, Alloc >

template<typename T, typename Mesh, Cubism::EntityType Entity = Cubism::EntityType::Cell, size_t RANK = 0, typename UserState = Block::FieldState, template<typename> class Alloc = AlignedBlockAllocator>
class CartesianMPI : public Cubism::Grid::Cartesian<T, Mesh, Entity, RANK, UserState, Alloc>
#include <CartesianMPI.h>

Cartesian MPI block (tensor) field.

Cartesian topology composed of block Field.h for the specified entity type. As opposed to an individual block Field.h, this class manages a structure of arrays (SoA) memory layout for all the blocks in the rank local Cartesian topology instead of just individual blocks. See the Cartesian.h grid section for a non-distributed variant of this class as well as the UserState extension.

Template Parameters

  • T: Field data type

  • Mesh: Mesh type to be associated with fields

  • Entity: Entity type

  • RANK: Rank of (tensor) fields

  • Alloc: Allocator for field data
