Detailed Description

Shared device-callable kernel implementations for the EulerP Evaluator.

Contains the per-element kernel functions (per-cell or per-face) that implement the computational core of each EulerP evaluation stage. These kernels are called from both the Host backend (via OpenMP loops in EulerP_Evaluator_impl.cpp) and the CUDA backend (via CUDA kernel launches).

Each kernel operates on a single element index range [i, iEnd) and uses the Portable sub-struct from the corresponding Evaluator_impl arg for data access. CUDA-specific shared memory buffers are conditionally compiled with DNDS_USE_CUDA.

Kernels defined here:

  • RecGradient_GGRec_Kernel_BndVal — boundary ghost value generation for gradient reconstruction
  • RecGradient_GGRec_Kernel_GG — Green-Gauss gradient computation (per-cell)
  • RecGradient_BarthLimiter_Kernel_FlowPart — Barth-Jespersen limiter for flow variables (per-cell)
  • RecGradient_BarthLimiter_Kernel_ScalarPart — Barth-Jespersen limiter for scalar variables (per-cell)
  • Cons2PrimMu_Kernel — conservative-to-primitive + viscosity (per-cell)
  • Cons2Prim_Kernel — conservative-to-primitive only (per-cell)
  • EstEigenDt_GetFaceLam_Kernel — face eigenvalue estimation (per-face)
  • EstEigenDt_FaceLam2CellDt_Kernel — face-to-cell eigenvalue accumulation + dt (per-cell)
  • RecFace2nd_Kernel — 2nd-order face reconstruction (per-face)
  • Flux2nd_Kernel_FluxFace — Roe inviscid flux computation (per-face)
  • Flux2nd_Kernel_Face2Cell — face flux scatter to cell RHS (per-cell)
