Among several Editions of Celeris under Celeria Wave Modeling Suite, Celeris Citius is the closest to the community version, Celeris Advent, with additional features such as:

HDF5 Logging: Citius writes data to disk in HDF5 format. The new logging system barely slows down the simulation and can easily imported by other software (e.g., MATLAB, Python, etc.)

Adaptive Timestep: Citius now runs on an adaptive time scheme. This means you can run your experiment with a relatively large timestep but let it resolve occasional extreme events that may cause model instability.

Better Boundary Condition: We improved the sponge layer boundary condition in Celeris Citius resulting in less reflection.

Hot Start: You can set times, in seconds, to take a snapshot of the experiment. Then you can restart the experiment from one of those snapshots.

Custom Overlay: Got a satellite image of the experiment area? You can now overlay it on the land.

Mouse Control: Move the camera using only the mouse with intuitive controls.

Duration: Set the duration of the experiment in seconds. Citius will shut down after the duration is reached.

Delayed Logging: You can delay logging by a given time in seconds, e.g., to start logging after the model warms up.

Log breaking: You can log more variables including dissipation value (wave breaking) and inundation (maximum water depth).

Minimized Mode: If you only care about logged data, start the experiment in minimized mode and let it run even faster.

Save Camera Position: Move the camera to a position you like and then save it's location for future runs.
