#### Classical stellar atmospheres

- Hydrostatic equation (+ dynamic pressure from MLT?)
- Constant energy flux
- Detailed non-local radiation transport (only 1D stratification)
- Convective energy flux from MLT

- Realistic Equation-Of-State
- Realistic Opacities
- Gravity

#### Dynamical multi-dimensional stellar atmospheres

- Hydrodynamic equations (dynamic pressure self-consistent)
- Dynamic energy equation
- Detailed non-local radiation transport (multi-D)
- Convective energy self-consistent

- Realistic Equation-Of-State
- Realistic Opacities (binned)
- Gravity
