Error in running examples

[ibrahim-hanif]

Description

I received the following error when trying to run the example 02_generate_openfast_ / iea15mw_semi (here)
and the same error in 03_design_* / tower_design_driver.py

Steps to reproduce issue

Files are the same as the latest repo on WEIS main

Code versions

• WEIS v2.1.2 (WEIS v2.1.2 #470 )

Hi,

It looks like you need to update your version of WISDEM to 4.2, and wisdem will require windio of at least 2.1.1.

I hope this helps.

Best, Dan

Thank you Dan! This solved the issue and now the example 02_generate_openfast_ / iea15mw_semi is running nicely :)

However, with that I also got the following warning:

DeprecationWarning: [c:\Users\***\.conda\envs\weis-env\Lib\site-packages\jsonmerge\__init__.py:27](file:///C:/Users/***/.conda/envs/weis-env/Lib/site-packages/jsonmerge/__init__.py:27)

...

Moreover, the code, when running on a interactive python notebook in vscode, seems to get stuck running for a long time after giving this warning:

Writing new controller parameter file parameter file: \\***\WEIS\examples\02_generate_openfast_model_for_dlcs\outputs/02_iea15_semi/0_strip_theory_modeling\openfast_runs\DLCsteady_0_weis_job_0_DISCON.IN.

due to the unclosed file preventing further commands or operations i suppose...

Interestingly enough, this isnt the case when I run the example python file as a script in the terminal...

Thank you for your assistance :)

Those warnings are normal. I have also seen that running simulations through a jupyter notebook is slower than expected.

Why was this the case, and how can this be corrected? would be grateful for you help, Thank you :)

[ibrahim-hanif]

Moreover, with regard the 02_generate_openfast.../iea15_semi_driver.py example

1. if possible, could you please explain slightly more what is the goal that is being met here in these examples, and what is happening behind the scenes? the docs give some idea but i'd like to learn more.

Could you please inspect and provide me with some solutions or work thoughts?

Thank you very much for your time!

For the tower design, I suggest you review the openfast outputs of the last runs. I've seen that error for short and steady state simulations, but thought it was resolved in the latest version of pcrunch.

For the strip theory semi-sub example, it's running SubDyn, which can resolve internal platform loads, but takes a long time to simulate.

For the hybrid model, the error message suggests you are missing dependencies:

    raise ImportError("The 'intersectMesh' option requires 'pygmsh' and 'meshmagick'. Please install them using 'pip install pygmsh==7.1.17' and 'pip install https://github.com/LHEEA/meshmagick/archive/refs/tags/3.4.zip'")

Hi Dan

I am trying to run the reference 15MW TLP designs (link) in RAFT (in WEIS through its OpenMDAO wrapper) using the example code on raft's getting starting page, but i encountered an error after running model = raft.Model( design );

when i compare these reference TLP files (eg. NREL_15MW_TLP_200m.yaml) to a 'raft design' output file made by weis (eg. raft_design_0.yaml; output of running examples/04_frequency.../04_umaine_semi), i see that weis' omdao_raft.py sets the member types to 'rigid' while the reference TLP files label them with a number (1,2,...)

(for reference, my full code can be found here called raft_learn.py)

1. could you please explain what these number types mean in the TLP reference files, as compared to from raft openmdao wrapper (eg. 1=fixed, 2=rigid, etc...)?
2. could you suggest ways to run the TLP reference files in the raft openmdao wrapper (in weis)?
3. could you also please suggest a potential path to model TLPs in weis ( from their geometry yaml file to raft modelling) for design optimization?

-- I am working in the Made4Wind EU project and aim to conduct design optimizations on our turbine design (TLP and a detailed geared drivetrain) (I've mentioned more info on the WISDEM issue #593)

Thank you very much for your time and consideration and I look forward to your reply,

[dzalkind]

Based on your code, you're using RAFT without WEIS. WEIS will create a RAFT model from a windIO geometry input.

The input files you have referenced are likely for a version of RAFT that is different from what you have. I suggest asking the maintainers of the model repo what RAFT version was used.
