Dear Alex,
In addition to the external shape, NuMAD requires that the composite laminate layup be defined. In effect, you would have to reverse-engineer the composite layup from the beam properties. Such reverse engineering would be worth while, and in fact, I think people have already done it before, as alluded to in the Sandia report found here: windpower.sandia.gov/other/113779.pdf. While I haven’t seen the composite laminate layup for the NREL (UpWind) 5-MW turbine myself, hopefully you can find it with a bit of research. I suggest you start by contacting the authors of the Sandia report. If you find the information, please post a link here on the forum.
Best regards,
