Dear Jason, I am using the spreadsheet of metocean data you provided and am attempting to form the Von Mises CDFs in MATLAB. Am I correct in saying the "Parameter 1" is mu the mean and "Parameter 2" is k the dispersion? Also do you know of any pre existing Von Mises CDF functions...

Hi Jason, Thank you for your swift reply. I am not running ROSCO separately however it may be running when I execute the .exe and .fst file. I am using TurbSim also.

Dr. Jonkman,

I'm not sure if I have to do anything other than what I have done in the image attached for the version flag?

Thank you for your help,
Breen

Dr. Jonkman,

I can run the openfast_win32.exe file, however I cannot run openfast_x64.exe or openfast_x64_double.exe. I get the error in the original attached image.

My machine is 64 bit so I don't know what is wrong. Do you have any suggestions?

Kind regards,
Breen Elliott

Dr. Jonkman,

Thank you for your help.
I compiled it myself. Am I correct in assuming that the Win32 file is the only .exe file suitable for windows?

Kind regards,

Hi All,

I am attempting to run openfast using the precompiled binaries, however I am receiving an error as seen in the attached image.

If anyone would be able to help I would really appreciate it!
