Detailed Description

template<int dim, typename number>
struct MeltPoolDG::CompressibleFlow::ConvectiveKernels< dim, number >

Convective kernel operations for compressible flow solvers.

This struct implements the evaluation of convective fluxes and their linearizations for compressible flow governed by the Euler or Navier–Stokes equations. It supports flux evaluation on both volume cells and faces.

It also provides functionality to compute the Jacobian (linearized form) of these fluxes, which is required for implicit schemes.
