Ontology file for UMaineSemi tower #97

Closed davidovitch closed 2 years ago

davidovitch commented 2 years ago

Is it possible that there is no ontology yaml description yet of the UMaineSemi tower? I can see there is OpenFAST/IEA-15-240-RWT-UMaineSemi/IEA-15-240-RWT-UMaineSemi_ElastoDyn_tower.dat for the OpenFAST model so I can of course also use that. I am currently converting an earlier version of the HAWC2 model with the UMaineSemi floater to fit/align with the recently re-organised/updated HAWC2 model. Once ready I will push it to a branch and submit a PR.

Are you looking for this line in the ontology?

davidovitch commented 2 years ago

It seems I didn't realise that UMaineSemi and VolturnUS-S are different names for the same floater. I have also seen another tower definition being used as the one linked from the ontology but I am not sure where that came from.

gbarter commented 2 years ago

Good point on the naming inconsistency. Certainly, if you find inconsistencies in the design definitions between the model files and ontology, please let us know!

davidovitch commented 2 years ago

I will close this issue and open another in case I find track down the origin of the other tower, and/or with the HAWC2 model of this floater/tower.

davidovitch commented 2 years ago

The reference report of the UMaine floating tower looks different than what is in the ontology. Has there been a re-design since the report was published, and is that what is in ontology yaml file? At least that seems what is going in this commit 1a1cbf57aeee5eff1e4ee99f0aafb16f4333fbc6. I also remember from @jennirinker the original tower+floater had an eigenfrequency close to 3P and had to be stiffened.

@davidovitch : Exactly. The original tower described in the report did not achieve the original design intent. It was modified in v1.1 (see release page and notes).

Thanks a lot for clarifying @gbarter
