How to Run the Two-Turbine VolturnUS-S_farm.yaml Case in RAFT

[ZADFAD]

Hello! When running the two-turbine case designs/VolturnUS-S_farm.yaml in raft_model, I noticed that certain code modules only support single-turbine operation. For example, at line 188, which defines the calculation of system properties in the unloaded state, it explicitly states that only single-turbine configurations are supported.
After reading the paper "Frequency-domain modeling of floating wind arrays with shared mooring lines", particularly Section 2 on frequency-domain modeling methods—which describes extending an existing baseline frequency-domain model to support array simulations and shared mooring functionality—I still couldn't figure out how to operate RAFT to run the VolturnUS-S_farm.yaml case. Could you provide detailed step-by-step instructions for this?#

Hi @ZADFAD

Good point, I made a note to add an example of the VolturnUS-S_farm.yaml case in the near future. In the meantime, could you take a look at the test case https://github.com/WISDEM/RAFT/blob/master/tests/test_data/VolturnUS-S_farm.yaml which is called by https://github.com/WISDEM/RAFT/blob/master/tests/test_model.py and see if that helps?

Hello! Thank you for your response. Do you mean that in the future you will add a new code example to directly run the VolturnUS-S_farm.yaml case, and in the meantime, can I start by learning the test_model.py code first?

Yes! My plan is to add this example in the near future, but I don't know exactly when. In the meantime, maybe the code in test_model.py can help you.
