Detailed Description

Host-side boundary condition handler managing all BC objects for a simulation.

Constructed from a list of BCInput specifications and a name-to-ID mapping. Automatically assigns default BC types for standard mesh zones (WALL, WALL_INVIS, FAR, and SPECIAL benchmark zones). Supports host/device transfer of all managed BCs.

Use id2bc(id) to look up a BC by zone ID, and deviceView<B>() to obtain a BCHandlerDeviceView for kernel invocation.

Constructor & Destructor Documentation

BCHandler()

DNDS::EulerP::BCHandler::BCHandler ( const std::vector< BCInput > &  bc_inputs, Geom::AutoAppendName2ID &  name2id  )

inline

Constructs the BC handler from JSON-deserialized inputs and a name-to-ID map.

Allocates BC slots for all zone IDs, applies user-specified BC inputs, then sets default types for standard zones:

• BC_ID_DEFAULT_WALL → BCType::Wall
• BC_ID_DEFAULT_WALL_INVIS → BCType::WallInvis
• BC_ID_DEFAULT_FAR → BCType::Far
• Special benchmark zone IDs → BCType::Special

Parameters

bc_inputs	Vector of BCInput specifications from JSON configuration.
name2id	Name-to-ID mapping from mesh zone names to integer IDs.

Exceptions

std::runtime_error

If a BC input name is not found in name2id.

Member Function Documentation

device()

DeviceBackend DNDS::EulerP::BCHandler::device ( )

inline

Returns the device backend where BCs reside (asserts all BCs are on the same device).

Definition at line 485 of file EulerP_BC.hpp.

deviceView()

template<DeviceBackend B>

t_deviceView< B > DNDS::EulerP::BCHandler::deviceView ( )

inline

Creates a device view of all managed BCs for kernel invocation.

Builds a host_device_vector of BC_DeviceView from each managed BC, transfers it to the specified device backend, and returns an owning t_deviceView wrapper. The returned object is move-only.

Template Parameters

B	Target device backend.

Returns

A t_deviceView<B> owning the device BC array.

Definition at line 542 of file EulerP_BC.hpp.

id2bc()

BC & DNDS::EulerP::BCHandler::id2bc ( Geom::t_index  id )

inline

Looks up a boundary condition by zone ID.

Parameters

id	Boundary zone identifier.

Returns

Reference to the BC object for the given zone.

Definition at line 463 of file EulerP_BC.hpp.

to_device()

void DNDS::EulerP::BCHandler::to_device ( DeviceBackend  B )

inline

Transfers all BC values to the specified device backend.

Parameters

B	Target device backend.

Definition at line 478 of file EulerP_BC.hpp.

to_host()

void DNDS::EulerP::BCHandler::to_host ( )

inline

Transfers all BC values to host memory.

Definition at line 470 of file EulerP_BC.hpp.
