Configuration reference

A configuration file defines the SPE11 case, physical model, grid, initial conditions, rock and fluid properties, wells, injection schedule, and OPM Flow command.

Use TOML for new cases. The legacy TXT format remains supported for existing configurations, but new configuration features are added only to TOML.

Start from a configuration in the examples or benchmark directory. Follow the Tutorial for a guided workflow, and use this section to look up exact variable meanings, units, accepted values, and restrictions.

Validation

pyopmspe11 validates the configuration before generating files. Validation covers required values, types, numeric ranges, array and matrix dimensions, well coordinates, expressions, saturation and rock properties, injection schedules, convective-dissolution settings, and case-specific requirements.
