Dear Sir,

Please find the attached image and help me to sort out the issue. Sorry for disturbing

Dear Mani,

The model appears to be going numerically unstable very quickly.

Did you make any changes to the OC3-Hywind model available from here: … Included in this archive is a version of FAST v7.02 with the Bladed-style DLL control interface and the changes necessary to accommodate the OC3-Hywind system–are you using this executable?

Best regards,

Dear Jonkman Sir,

Thanks for immediate reply. Now its working.

Thanks alot
