Celeris Citius

Faster than ever.

Celeris Citius is the paid version of Celeris Advent. Based on your feedback, we incorporated new features such as:

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

Adaptive Timestep: Celeris can now run 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. Celeris 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.
