Plot3DファイルからOpenFoam形式への変換(Plot3DToFoamコマンド)

適当なケースフォルダ上(tutorials/incompressible/simpleFoam/airfoail2Dなど)で plot3DToFoamコマンドを実行

[waku@centosvm airFoil2D]$ plot3dToFoam -help

Usage: plot3dToFoam [OPTIONS]
options:
-2D use when converting a 2-D geometry
-case

specify alternate case directory, default is the cwd
-noBlank skip blank items
-noFunctionObjects
do not execute functionObjects
-scale geometry scaling factor - default is 1
-singleBlock input is a single block
-srcDoc display source code in browser
-doc display application documentation in browser
-help print the usage

Using: OpenFOAM-2.0.x (see www.OpenFOAM.com)
Build: 2.0.x-eee91f6cb684

今回は、マルチブロック(デフォルト)でBlank情報がないので、-noBlankオプションと、-scaleオプションのみ利用する。

[waku@centosvm airFoil2D]$ plot3dToFoam -noBlank -scale 1 P3D.xyz
