Running FAST from Command Prompt


I’m trying to run the DTU 10 MW RWT from the command prompt using the input below, but get the error below:

'D:\FAST1\bin\FAST_Win32.exe D:\FAST_Runs\OP_Test_16DT\test.fst ’

FAST_InitializeAll:SrvD_Init:BladedInterface_Init:The dynamic library
D:\FAST_Runs\OP_Test_16DT\10MWRWT\ServoData\dtu_we_controller_bladed.dll could not be loaded.
Check that the file exists in the specified location and that it is compiled for 32-bit
applications. [/code]

I can run the exact same file by simply dragging the .fst file onto the exact same FAST_Win32 executable without any issues.

To troubleshoot, I have also been able to run the files in the CertTest folder in the command prompt with any issue. So I believe that my input formatting is correct.

If anyone could suggest a reason why I get the error when running through the command prompt or any other avenues for troubleshooting, I’d greatly appreciate it!


Dear James,

Is this the correct path to the DLL?:

Do you specify the full path when specifying DLL_FileName in the ServoDyn input file?

Best regards,

Hi Dr. Jonkman,

Thank you for your quick reply!

I’ve found a workaround for the issue by moving the FAST exe and MAP.dll files to the directory and using relative file paths instead of absolute to execute the command.
