### [ post_foil_cfl3d ]

post_foil_cfl3d(path, j0, j1, nHi=40, fname=’feature2d.txt’)

Read in CFL3D foil result and extract flow features.

path: folder that contains the output files j0: j index of the lower surface TE j1: j index of the upper surface TE nHi: maximum number of mesh points in k direction for boundary layer

Single C-block cfl3d.prt index

i : 1 - 1 symmetry plane j : 1 - nj far field of lower surface TE to far field of upper surface TE k : 1 - nk surface to far field

### [ feature_xfoil ]

feature_xfoil(cst_u, cst_l, t, Minf, Re, AoA, n_crit=0.1, fname=’feature-xfoil.txt’)

Evaluate by xfoil and extract features.

cst-u, cst-l: list of upper/lower CST coefficients of the airfoil. t: airfoil thickness or None Minf: free stream Mach number for wall Mach number calculation Re, AoA (deg): flight condition (s), float or list, for Xfoil n_crit: critical amplification ratio for transition in xfoil fname: output file

Dependencies:

cst_modeling, xfoil
