It’s the first time that I write on this forum. I’m a engineering student in Korea, and a beginner of using FAST.
I have a problem that I cannot solve by myself well.
I want to simulate some cases with the “NRELOffshrBsline5MW_OC3Hywind” type.
I made my own wind files by using TurbSim, (mean V = 10ms, IECKAI type) and i use other factors with the files from the public directory folders. When I set the platform model to 0, it runs well, but when I set the platform model to 1 or 3, error is occurred. (Below)

I change some input values to correct the grid area. but it doesn’t work well. How can I solve this problem?
Thanks to your help
