CLI limits

The CLI documentation says per-region separate `.ode` files and changing ODE parameters during a run are future work, and some demos are not yet fully reproducible through the CLI.Read 11 Oct 2026 · finsberg.github.io

Command line

The `beat` command line tool runs tissue-level Monodomain simulations and postprocessing from a `config.toml` file.Read 11 Oct 2026 · finsberg.github.io
