Frequently used CFD post procedures.
### [ 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 fname: output file name. If None, then no output tecplot: if True, then convert cfl3d.prt to surface.dat
- 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 name. If None, then no output
cst_modeling pip install cst-modeling3d xfoil pip install xfoil
- Re: Reynolds number in case the simulation is for a viscous flow.
In case not informed, the code will assume inviscid.
- Minf: Mach number in case the simulation has to take in account compressibility
effects through the Prandtl-Glauert correlation. If not informed, the code will not use the correction. For logical reasons, if Mach is informed, a Reynolds number different from zero must also be informed.
### [ feature_TSFoil ]
- Evaluate by TSFOIL2 and extract features.
cst-u, cst-l: list of upper/lower CST coefficients of the airfoil t: airfoil thickness or None Minf, Re, AoA (deg): flight condition (s), float or list fname: output file name. If None, then no output
cst_modeling pip install cst-modeling3d pyTSFoil pip install pyTSFoil
