Running Offshore ITI Barge Files

I am trying to run the full simulation and progressing after having done some file additions/ movements to the original downloaded folder ITIBrg4. However I am now stuck on the error “ff wind array boundaries violated. Grid too small in z direction z = 92.8 64 m is above the grid. Error getting velocity in aerodyn/ad_windvelocitywithdisturbance ()”

In which input file is the “grid” established so i can fix this? Thanks


Given the fact that you’ve moved some files around, I would guess that you are pointing to the wrong wind file. What wind file are you using? It’s specified in the AeroDyn input file.

Will check … How can I attach a screen shot of the error? Thanks

Hi Peter, Jason

I ma also getting same error (for land based NREL 5MW wind turbine simulation) regarding Grid too small in Z direction. Please see my post here [url]Wind data of the FAST certification tests]

I request your help to progress.



I’ve now answered your question in the other forum topic. Please don’t post the same questions twice. We will respond when we can.

Best regards,

Hi Jason
