Sorry to bother you, may I ask if you have a user manual for the BLAST BLade Aeroelastic Stability Tool(BLAST)
Hi HongJieSu, No bother at all. Have seen page 72 of:

Hello, sir, I used BLAST to analyze the flutter of the blades of a 5MW wind turbine. I can't tell the meaning of the lines in the drawing, because the legend information is not given in the drawing. I seek your help. How can I tell whether the flutter has occurred and what is the flutter frequency? The result is shown in the figure.
How to distinguish which first order mode each line segment represents from the Campbell plot obtained by NUMAD using the Fluttle Tool calculation without a legend?
