はじめに

こちらの記事を参考にccmToFoamを利用しようとしたところ，リンクが変わっており，探すのに苦労したので，こちらで記事にしておきます．

環境： Ubuntu 18.04.3 LTS (Mac(Catalina)上のParallesDesktop14環境)
バージョン：OpenFOAM v1906

ビルド

libccmio-2.6.1の場所が，かなり変わっており，苦労しました．
以下のリンクにあるようです．
http://visit.ilight.com/svn/visit/trunk/third_party/

cd ThirdParty-v1906/
wget http://visit.ilight.com/svn/visit/trunk/third_party/libccmio-2.6.1.tar.gz
tar zxvf  libccmio-2.6.1.tar.gz 
./makeCCMIO

実際は，OpenFOAM-v1906/applications/utilities/mesh/conversion/ccmのAllwmakeを叩けばいいのですが，共有ライブラリが見えなかったりで面倒な場合は，以下のようにした方が確実です．

cd ../OpenFOAM-v1906/
./Allwmake

以下のようなlogが途中出力されていきます．

wmake foamToCcm
make[3]: Entering directory '/home/parallels/OpenFOAM/OpenFOAM-v1906/applications/utilities/mesh/conversion/ccm/foamToCcm'
Making dependency list for source file foamToCcm.C

動作確認

問題なくビルドできたら，以下のコマンドで動作確認をします．

ccmToFoamのテスト

$ ccmToFoam -help
Usage: ccmToFoam [OPTIONS] <ccm-file>
Arguments:
  <ccm-file>        The input .ccm or .ccmg file
Options:
  -ascii            Write in ASCII format instead of binary
  -case <dir>       Specify case directory to use (instead of the cwd)
  -export           Re-export mesh in CCM format for post-processing
  -list             List some information about the geometry
  -merge            Merge in-place interfaces
  -name <name>      Provide alternative base name when re-exporting (implies
                    -export). Default is <meshExport>.
  -noBaffles        Remove any baffles by merging the faces
  -numbered         Use numbered names (eg, patch_0, zone_0) only
  -remap <name>     Use specified remapping dictionary instead of
                    <constant/remapping>
  -scale <scale>    Geometry scaling factor - default is 1 (ie, no scaling)
  -solids           Treat any solid cells present just like fluid cells. The
                    default is to remove them.
  -doc              Display documentation in browser
  -help             Display short help and exit
  -help-compat      Display compatibility options and exit
  -help-full        Display full help and exit

Reads CCM files as written by PROSTAR/STARCCM and writes an OPENFOAM  polyMesh.
Multi-region support for PROSTAR meshes should be stable. Multi-region merging
for STARCCM meshes will not always be successful.

Using: OpenFOAM-v1906 (1906) (see www.OpenFOAM.com)
Build: v1906
Arch:  LSB;label=32;scalar=64

foamToCcmの動作テスト

$ foamToCcm -help
Usage: foamToCcm [OPTIONS]
Options:
  -case <dir>       Specify case directory to use (instead of the cwd)
  -constant         Include the 'constant/' dir in the times list
  -latestTime       Select the latest time
  -mesh             Convert mesh only
  -name <name>      Provide alternative base name. Default is <meshExport>.
  -noZero           Exclude the '0/' dir from the times list
  -overwrite        No backup of existing output files
  -remap <name>     Use specified remapping dictionary instead of
                    <constant/remapping>
  -results          Convert results only
  -time <ranges>    List of ranges. Eg, ':10,20 40:70 1000:', 'none', etc
  -doc              Display documentation in browser
  -help             Display short help and exit
  -help-compat      Display compatibility options and exit
  -help-full        Display full help and exit

Translate OPENFOAM data to CCM format

Using: OpenFOAM-v1906 (1906) (see www.OpenFOAM.com)
Build: v1906
Arch:  LSB;label=32;scalar=64

念のため，tutorialのpitzDailyに対して動作確認

foamToCcm -mesh

最後に

もし利用された方は，動作確認して問題なく動作したStar-CCM+のバージョンを教えてもらえると，記事の作者は喜びます．（もちろん動作しなかったバージョンも）
