OpenFast Regression tests

Postby Romain.Pinguet » Tue Feb 27, 2018 6:03 am

Dear all,
I just installed OpenFast on My MacOS. I tried to execute the regression tests as described in the manual. Most of the tests passed however all the tests using HydroDyn fail. I have very high values of the infinity norms for some channels when it is compared to the baseline results.
Do you have any idea why ?

Thank you for your help,

Romain

Dear Romain,

Could this be related to the following open issues in OpenFAST?:

Dear Jason,

It is probably the problem. I did not see your posts on GitHub. Thank you for that.
However, When I write RanLux as keyword for the WaveSeed, I have got an error : Invalid numerical input for file.
Do I have to modify the code somewhere else ?

Thank you very much,

Romain

Dear Romain,

The OpenFAST issue #89 (https://github.com/OpenFAST/openfast/issues/89) is an enhancement that I've proposed be implemented in HydroDyn to resolve the problem you and others have reported. However, this enhancement has not yet been implemented in source code. It is proposed future work.

Dear all,

I'm trying to run some of the Regression Tests with OpenFAST on Cygwin64, e.g. for the 5MW_OC4Jckt_DLL_WTurb_WavesIrr_MGrowth test, but i keep getting the same error: Segmentation fault (`core' generado), without changing any input file. Could someone help me please?

I'll leave a screenshot so you can see in more detail.

Thank you very much.

Juan

Dear Juan,

I'm not familiar enough with Cygwin to know the answer to your question. I suggest posting your question on OpenFAST github issues (https://github.com/OpenFAST/openfast/issues) to ensure that it is read by others on the OpenFAST team who may not check this forum regularly.

Dear Jason,

I'm trying to run the test by other means, different from using it on Cygwin64, but now the simulation doesn't end. It just stays in the "Timestep: 0 of 60 seconds." step of the simulation. Can you help me please?

Thank you.

Dear Juan,

I'm not familiar with OpenFAST simply "hanging" at time zero. Perhaps the controller is not loading properly and is causing the simulation to hang? Can you run the simulation without the controller by setting CompServo = 0 in the FAST primary input file and GenDOF = False in the ElastoDyn primary input file?

Dear Jason,

I've just done what you suggested, running the simulation without the controller, but now I encounter this problem (In attached). I guess I have to add those parameters that FAST can't allocate to the Hydrodyn input file, but where? I've been inspecting the Hydrodyn file but I still can't figure it out.

Best regards.

Dear Juan,

Your screenshot is reporting an error about "allocating space", which is a question that has recently been answered in the following forum topic: viewtopic.php?f=13&t=2097&p=11433.
