Solving steady state implict advection diffusion Equation using AMReX

[ankithadas]

Hey AMReX team,

I am planning to use AMReX to solve the steady-state, incompressible, constant-density Navier-Stokes Equations in 3D. I thought I would start with something simple, like steady-state advection-diffusion, and progress to something more complex. While exploring AMReX, it seems that most solvers are time-dependent, and steady-state solutions are generated by time-integrating until the relative difference becomes small. My question is, does AMReX provide implicit tools for implicit advection? If not, how should one approach solving advection-diffusion implicitly (not IMEX)?

Kind regards,
Ankith
