Re: MIT/NREL TLP without wind

Dear Jason, Thanks for sharing your time. The problem is solved after switching WaveDirMod from 1 to 0. It is stated that WaveDirMod is only used when WaveMod=2,3, or 4. I didn't switch it off, continued with the default switch, while changing WaveMod from "2" to "1". And didn't ...

Re: MIT/NREL TLP without wind

Dear Jason, Thanks for your help and suggestions. I have checked all the settings in the input files and the fst file (Test23). Since I'm using the default settings, everything looks ok. I've also checked the HyrdoDyn Manual regarding on regular wave analysis. Unfortunately, I'm getting a zero respo...

Error calculating the wind speed at position

Dear All, I am trying to see the response of the MIT/NREL TLP under steady wind conditions. I am simply executing Test23.fst file with only setting Windtype=1 from InflowWind INPUT FILE. Execution is aborted with the message below. I did not change anything in source codes except the WindType. I am ...

Re: Invalid numerical input for file

Dear Mustafa, WindType=2 in the InflowWind module of FAST v8 and OpenFAST requires a simple text-based wind data file. Please see my post dated Mar 05, 2014 in the following forum topic where I provide an example of a uniform wind file with wind-speed steps: https://wind.nrel.gov/forum/wind/viewtop...
