Detailed Description

Host-side physics object managing gas parameters and device-transferable reference values.

Stores a host_device_vector of reference values (e.g., freestream quantities) and PhysicsParams. Supports JSON serialization and host/device transfer for GPU offloading. Use deviceView<B>() to obtain a PhysicsDeviceView for kernel invocation.

Member Function Documentation

device()

DeviceBackend DNDS::EulerP::Physics::device ( )

inline

Returns the current device backend where reference values reside.

Definition at line 362 of file EulerP_Physics.hpp.

deviceView()

template<DeviceBackend B>

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