## Contribution

It highlights the feasibility of realistic local and global simulations for brown dwarf atmospheres and addresses key numerical challenges involved.

## Key findings

- Simulations can realistically model brown dwarf atmospheres.
- Local and global models are both feasible with current techniques.
- Numerical challenges include handling large dynamic ranges and radiation scattering.

## Abstract

We discuss prospects of using multi-dimensional time-dependent simulations to study the atmospheres of brown dwarfs and extrasolar giant planets, including the processes of convection, radiation, dust formation, and rotation. We argue that reasonably realistic simulations are feasible, however, separated into two classes of local and global models. Numerical challenges are related to potentially large dynamic ranges, and the treatment of scattering of radiation in multi-D geometries.
