Attribute Use for the construction of xxx.avl

The following list of attributes drives the AVL geometric definition. Each FaceBody which relates to AVL Sections will be marked up in an appropriate manner to drive the input file construction. Many attributes are required and those that are optional are marked so in the description:

The AVL Sections are automatically generated, one from each FaceBody and the details extracted from the geometry. Xle, Yle, and Zle, are taken from the Node Associated with the Leading Edge. The Chord is computed by getting the distance between the LE and TE (if there are 3 Edges in the FaceBody the TE point is considered the mid-position on that third Edge). Ainc is computed by registering the chordal direction of the FaceBody against the X-Z plane. The airfoil shapes are generated by sampling the Curves and put directly in the input file via the AIRFOIL keyword after being normalized.
