Wind files generated using TurbSim under macOS cannot be used, but windows can. #2028

Open Melancho7ee opened 7 months ago

Melancho7ee commented 7 months ago

Dear All Bug description I am using OpenFAST+Simulink to simulate a 5MW ITIBarge offshore wind turbine in my MacBook (M1 chip). And I tried to generate turbulent wind "*.bts" file, using Turbsim in my MacBook (M1 chip). However, If I use TurbSim to generate a bts file in a macOS environment, it cannot be used. The Simulink error message is as follows. f7d6f3c4b2031723bfc2dac1f7ea0f20

By contrast, I tried to use the same *.inp file* to generate a .bts wind file in a windows environment**, and then copied it to my MacBook for use. The strange thing is that the wind file generated in this way can be used.

I don’t understand the reason for this. Is this a bug of TurbSim in the macOS environment?

Best regards,

Dear @Melancho7ee,

Which version of OpenFAST are you using? Does upgrading to the main branch of OpenFAST (currently release OpenFAST v3.5.2) resolve the issue?

Best regards,

I am using OpenFAST v3.5.0, and Matlab r2023b now. I do not but will try later on v3.5.2. Thanks!

Best regards,

Dear @Melancho7ee,

Can you share your TurbSim input file, and exactly which compiler setup you are using on the Mac?

Dear @andrew-platt,

The compiler setup is:
