Detailed Description

template<int dim, typename number, ConvectionKernelType Kernel, typename VectorizedArrayType = dealii::VectorizedArray<number>>
struct MeltPoolDG::Utils::DGConvectionOperator< dim, number, Kernel, VectorizedArrayType >

Generic discontinuous Galerkin operator for pure convection problems.

The physical convective flux is defined by a user-provided kernel, which specifies how the flux is computed from the local solution state. Interface contributions are evaluated using a Lax–Friedrichs numerical flux to ensure stability.
