Detailed Description

template<int dim, typename Number, typename CaseClass>
class MeltPoolDG::Simulation::SingleTrackMelt::SimulationSingleTrackMelt< dim, Number, CaseClass >

Simulation case for a single-track melt problem.

This class defines the case-specific parameters, mesh generation or import, boundary conditions, initial field conditions, and optional local refinement regions for the single-track melt setup.

The implementation considers the single-track melt configuration presented in:

Constantin Zenz, Peter S. Cook, Laszlo Vörös, and Andreas Otto, "A critical comparison of one- and two-fluid approaches for the simulation of laser-induced melt pool formation and vaporisation", Discover Materials, 2025.

Template Parameters

dim	Spatial dimension.
Number	Scalar number type.
CaseClass	Base case class, for example MeltPoolCase or HeatTransferCase.
