In this page you can find a manual pages for Opal and its programs.

- opal.1 Opal - system for molecular modelling
*(general introduction. You should visit the About Opal page first)*. - opal_singlept.1 singlept - compute the potential energy value for a given coordinates.
- opal_lmin.1 lmin - compute a local minimum of the potential energy.

**opal_internals**Opal data structures and library functions**opal_gmin**gmin - compute a global minimum via the simulated annealing.**opal_gmin_t**gmin_t - compute a global minimum of the smoothed energy function.**opal_lmin_t**lmin_t - compute a local minimum of the smoothed energy function.**opal_singlept_t**singlept_t - compute the smoothed energy function for a given coordinates.
