| # Numerical Manufacturing And Design Tool (NuMAD) | ||
| NuMAD (Numerical Manufacturing And Design) is an open-source software tool written in MATLAB which simplifies the process of creating a three-dimensional model of a wind turbine blade. The graphical, user-friendly tool manages all blade information including airfoils, materials, and material placement. NuMAD uses the blade information to generate input files for other tools: | ||
|
|
||
| The ANSYS® commercial finite element package | ||
| The NWTC codes PreComp, BModes, and FAST | ||
| PLOT3D file format for CFD mesh building | ||
|
|
||
| When used in conjunction with these other tools, NuMAD provides computation of blade cross section properties, analysis of blade buckling, and estimation of blade aeroelastic instability. The user’s manual (SAND2012-7028) describes the capabilities and usage of NuMAD. |

| NOTE ON AIRFOILS USED IN THESE EXAMPLES: | ||
| ========================================================================== | ||
|
