Octopus

A tool for fast Lagrangian trajectory calculation

This fortran code is used to calculate particle trajectories using three dimensional velocity fields from numerical models, e.g., MITgcm (https://github.com/MITgcm/MITgcm). The current version is setup based on C-grid.

You can find preliminary documentation here: Wiki

Current status: testing the volume conservation.
