Dear @fronterapp , when I setting a case and can run in turbinesFoam .but when I use your codes :floatingTurbinesFoam to run the wind turbines case ,which error ,I don't know why .I hope you can help me.

Dear Chen, unfortunately I cannot run the case myself at the moment. Could you provide the log file of your run?

Dear @fronterapp I'm sorry for replying so late，the log file the log file is shown below.I don't understand why the program suddenly stops. pimple.log

Dear Chen,

It looks like there's an issue when calculating the end effects, particularly with the application of the exp() function here: https://github.com/fronterapp/thesis-FloatingTurbine/blob/a4a4e188f09d983d5776772f9781082349d7e2ae/libraries/floatingTurbinesFoam/src/fvOptions/axialFlowTurbineALSource/axialFlowTurbineALSource.C#L541-L548 It seems that the issue might be related to the phi angle being either 0 or π, which can lead to a division by zero when calculating the end effects.

Could you try disabling the end effects in fvOptions and running the case again? If the run proceeds without issues, I recommend enabling the debug flag to get more detailed information about what's happening inside the function.

Let me know how it goes!

Best regards, Pere
