From what I understand, external software where used to simulate the water and wind current. Then this data is transformed into an occupancy grid using the python scripts windLBP.py and water_HECRAS.py
I reckon Paravisi used t3.p01.hdf as a water velocity field, along with a .yaml file. It is said in his paper that the Hec RAS simulator was used.

After that one needs to rosrun water_current windLBM.py [path_to_yaml_file]
The python scripts first creates the occupancy grid with all the fluid speed vector field, and then creates a service host so that the FreeFloatingPlugin attached to your boat can ask what is the local value of the water current.

In /home/akr-bdx/NAFEA/usv_sim_lsa_ws/install_isolated/share/water_current/maps/HECRAS/diluvio1.yaml
the path of the .hdf file has been set manually to /home/paravisi/hecrasmaps/diluvio1-7m/

I suspect they either forgot to submit the file (which is unlikely as it was already in the /home/akr-bdx/NAFEA/usv_sim_lsa_ws/install_isolated/share/water_current/maps/ folder), or they couldn't publish it publicly for IP reasons.

hello,
I would like to ask about the .hdf files to be able to make the simulations present in the project, how could I access them? or how could I execute one of the tests proposed in the project?
thank you.
