Generating OpenFAST inflow from Open FOAM

Wind & Water Inflow Turbulence
7

Dear Jason,

Thank you so much for your guidance. I followed your post on converting VTK format to HAWC format. I read about the number of grids in this post [OC3 turbulence model(Mann model) - #4 by Jason.Jonkman] and set them accordingly. However, I could not run the simulation successfully. The simulation error is shown as follows.

Best regards,
