Problem in running pisoFoamTurbine.ALMAdvancedOpenFAST

[Simon7537]

I tried running the case in exampleCases/example.NREL5MW.ALMAdvancedFAST8, but the following error occured:

My OpenFOAM version is 2.4.x.
My OpenFAST version is 2.1.0, and I had replaced the 5MWBaseline directory in the case with OpenFAST-2.1.0.
And OpenFAST can be successfully ran in the case directory if CompInflow option changes to 1.

OS: CentOS 7
Compilers: gcc 5.2.1

Thanks for the help.

The relevant error line is:

[1] nFASTSubSteps has to be the same for all turbines

Make sure your sub-time steps from openfast are all consistent.

Thank you for your fast reply!
But I only set 1 turbine in constant/turbineArrayProperties, and the nFASTSubSteps=dt(OpenFOAM)/dt(OpenFAST). Are there any other problems or any other options can set nFASTSubSteps?

Hello, have you solved this problem? It seems that the problem is here: Aerodyn doesn't want to calculate forces on the tower. All actuator points on the tower are turned off for turbine 0. You can change the TwrAero in AeroDyn in 5MWBaseline to True. Maybe it can help you solve the problem.

[Tanjunyao2000]

Hello, may I ask how you finally solved this problem? I'm also encountering the same issue — I've set up only one wind turbine, and my OpenFOAM deltaT is 0.01, OpenFAST DT is 0.0025, and nFASTSubSteps is set to 4.

我尝试在 exampleCases/example 中运行 case。NREL5MW。ALMAdvancedFAST8，但出现以下错误：
