A question about the LIDAR measurement output #197

Open DavidChen0429 opened 2 months ago

DavidChen0429 commented 2 months ago

Hey,

I am new to OpenFAST, and I am writing this to ask a question about the LIDAR measurement output. I wanted to visualize the LIDAR (sensorType: continuous) output of the IEA-15-240-RWT-Monopile turbine. When I didn't add any output the simulation ran successfully, but after adding "WindMeas1" in inflowFile.dat, I got an error like this: image

Does it mean that the turbine is unable to visualize the LIDAR output? If so, is there an alternative way to visualize it?

This question might be better direction at the NREL Forums, which also might be a good place to search for prior questions on the Lidar output capability. I will forward your question along.

Dear @DavidChen0429,

The errors are imply that you are defining outputs in the OutList of InflowWind that do not exist. I would guess there is a formatting issue in your input file, e.g., not putting quotes around "WindMeas1".

In general, to debug errors in input file formatting, you can enable the Echo option to debug.

Best regards,

Dear @jjonkman,

Thanks for the help, I did notice a typo when copying the wind sensor measurements parameter from the OutListParameters.xlsx, and now it finally works.

Maybe a follow-up question about the LIDAR, I am a bit overwhelmed by the parameters in the inflowfile.dat about LIDAR, I think it would be very helpful if there exists documentation about LIDAR in OpenFAST, do you happen to know where I can find it?

Best regards, David

Dear @DavidChen0429 ,

I’m not aware of published documentation on the LiDAR functionality added to the InflowWind module in OpenFAST v3.5. I would suggest posting your question(s) on the OpenFAST GitHub repository (https://github.com/OpenFAST/openfast/discussions) and hopefully one of the developers can answer them. (I don’t personally have experience with this module myself.)

Best regards,
