I’m trying to analyze the forces that could appear during the installation of a three bladed wind turbine in Fast v7. For that, I’ve tried to make a model with just one blade and another one with two but with 120 degrees between them.
In the first try, I specified just one blade file (blade.dat) in the slots of the primary file (.fst). In this case, when I tried to run Fast appeared an error explaining that I have to specify the three files to continue.
On the second try, I specified the three blades but I tried to despise one of them decreasing its mass a lot. In this case, the issue was that appears to be a mathematical problem, because the program reports that there are some blade elements in supersonic or just doesn’t report any valid value (NaN results).
My question is, is there any way to analyze a wind turbine during its installation? (first at all with just the tower, secondly one blade in different positions and finally two blades)
Thank you in advance,
