Problem with Crunch - column reference

Hi, I'm trying to run Crunch, but it appears the following error: "Your expression seems to be making an invalid data column reference" Error_Crunch.png So, my question is about how it orders the columns. At the file .out, I think that column 1 is Time (s) and column 2 is Wind1VelX (m/s). ...

Re: Error with the FF wind array boundaries

Hi !

I only have changed the azimuth to 180 due to another previous error in a different case. The rest is exactly like in the originals file.

Re: Error with the FF wind array boundaries

Hi Jason, Thank you for your answer. I understood that the error is due to the small grid in Z direction. In the example above, there is a Z=177,22 m that is above the grid which goes up to 172,5 m above the ground. The problem is that there is always a node above the grid defined. I listed some def...

Re: Error with the FF wind array boundaries

Hello, I'm doing a simulation with OC3Hywind and for some DLC I have the error: "Grid too small in Z direction". I tried to increase the grid height in the turbsim file, but it only change the inferior limit of the grid. Even if I change the grid size, the higher point of the grid continue...

Error: There is no valid value of Phi for these operating conditions – Problem to update AeroDyn

Hi, I’m working on a Spar Structure – OC3 Hywind. I’m using the files from C:\...\FAST\OWT\model01\5MW_Baseline, but when I run the DLCs it appears the error “there is no valid value of phi for these operating conditions”. I looked at the forum and I understood that I have to update the AeroDyn to v...
