Generating only Cp_Ct_Cq table and new .IN file from WindIO

[TheMercer]

Description

Hi, so I am trying to generate a new Cp_Ct_Cq table and .IN from WindIO.

Closest examples our example 5 & 6. Which generating new OpenFast model, which is great also. However it also always wants to generate BTS files and run LC even tho I get rid of the DLC dict in model.yaml.

Steps to reproduce issue

Please provide a minimum working example (MWE) if possible

1. Run example 5 or 6
2. Remove DLC dict from model.yaml
3. …

Current behaviour

It will generate the model but then generate BTS files and run DLCs

Expected behavior

Generate OpenFast model, new Cp_Ct_Cq and .IN, then stop

Code versions

List versions only if relevant

• Python
• …

If you could help, give example or show how I can go from WindIO to OpenFast + Cp_Ct_Cq + .IN without having to make BTS files. Much appreciated

[gbarter]

You are correct. The call to turbsim is hardcoded no matter what the OpenFAST CompInflow or InflowWind-WindType settings are. That might take just a bit to correct. Is TurbSim not working for you?

[TheMercer]

It works. It's just slow, and I don't need it. So ideally it wouldn't run, unless a flag was said maybe. As I just want the table and .IN without running OpenFast

[TheMercer]

Unless you have a away to generate, Performance table and new .IN file without having to generate BTS files ?

[gbarter]

Yes, I also see that those OpenFAST files are only generated once TurbSim is done. I could start a feature branch to fix this issue if that helps.

[TheMercer]

Yeah, because atleast I could just kill the process after those files are made.

I think having BTS files first when you don't know the OpenFast is 100% correct yet (due to what ever changes are being made).

Or at somepoint make it possible to have a flag for turbsim files ?

[gbarter]

I will see what I can do. . .

[TheMercer]

If you know ish where that lives. I can always see as well and try and help also

[TheMercer]

So it doesn't "break* other people's runs. You have that flag as true by default. So original functionality is kept. Just can be disabled

[dzalkind]

There is a model_only flag in the modeling options that should skip the simulations: https://github.com/WISDEM/WEIS/blob/77512f2244be4e445425b107c4c40d67326cfaed/weis/inputs/modeling_schema.yaml#L39

https://github.com/WISDEM/WEIS/blob/77512f2244be4e445425b107c4c40d67326cfaed/weis/aeroelasticse/openmdao_openfast.py#L610

[TheMercer]

Would this skip the BTS generation ? Or could we move bts generation into that ?

[TheMercer]

I will try that tomorrow, and see if that doesn't generate bts files. (Hopefully not)

[dzalkind]

Here is where the BTS files are generated: https://github.com/WISDEM/WEIS/blob/77512f2244be4e445425b107c4c40d67326cfaed/weis/aeroelasticse/openmdao_openfast.py#L1821

It should skip that. My personal workaround would be to only make one short BTS file, like in this example. That should not take much computing time.

[TheMercer]

I will try that also, if it does make BTS files

[TheMercer]

Thank you both for your prompt response.

@dzalkind Model_only to true worked, thank you on that one.

@gbarter and dzalkind, also highlighted a bug ?

Airfoil number 59 tab number 0 has the moment coefficient different between +-180 deg. This is changed to be the same now.

[gbarter]

Thank you- we will have to check that one out.

[dzalkind]

I pushed a fix in #302.
