Detailed Description

Top-level solver orchestrator for compressible Navier-Stokes / Euler simulations.

Provides the EulerSolver class template which owns and coordinates all solver components: mesh infrastructure, variational reconstruction, the EulerEvaluator spatial discretization, DOF arrays, ODE integrators, linear solvers (LU-SGS / GMRES), and I/O subsystems.

Responsibilities include:

  • JSON-based configuration loading, merging, and validation
  • Mesh reading (serial CGNS or distributed), partitioning, order elevation, and bisection
  • Solver initialization (evaluator, DOF allocation, restart loading)
  • Implicit time-marching loop (dual time stepping, CFL ramping, convergence monitoring)
  • VTK/HDF5/Tecplot data output and restart I/O
  • Time-averaging for unsteady statistics

Supported model specializations (via EulerModel enum): NS, NS_2D, NS_SA, NS_SA_3D, NS_2EQ, NS_2EQ_3D, NS_3D
