Corewind - Tow to port config not working [WTG is not in list]

[Filip-OWF]

Hi

Trying to reproduce the corewind tow to port case. Before starting my own simulations. When running it I get a simulation failed message as below.

Is this something that has been experienced before?

Regards Filip

library_path =  Path(r."WOMBAT\library\corewind")
config = load_yaml("corewind/project/config", "morro_bay_tow_to_port.yaml")
sim = Simulation(library_path=library_path, config=config, random_seed=2023)
sim.run()

Simulation failed at hour 118,560.500503, simulation time: 2015-07-12 00:30:02

The above exception was the direct cause of the following exception:

Hi @Filip-OWF, thanks for identifying this! I'd identified recently on my end as well, and am actively working on diagnosing this issue.

[RHammond2]

Hi @Filip-OWF I may have actually addressed this issue in one of the many updates that are on the develop branch. Would you be able to install wombat from there and confirm if this is still an issue for you?

[Filip-OWF]

Hi @RHammond2 Thank you for taking your time. This has solved my issue. Which is not present in the latest version available in the develop branch.

Regards, Filip

Thanks so much for confirming!
