#はじめに
OpenFOAMのユーザーマニュアルは網羅的ではない。というよりも入門書に相当するドキュメントだと思うし、最大のドキュメントはソースコード自身だったりする。
読んでいるとたまに使い方や設定項目で載っていないものがあったりするので、その探し方の一方法についてのメモ。
#例：foamDataToFluent
OpenFOAMの結果をFluentのGUI上で見れるように変換するユーティリティ。
ユーザーマニュアルには下の表が乗っている。
(https://cfd.direct/openfoam/user-guide/v3-fluent/#x32-1970006.3)
| Fluent name | Unit number | Common OpenFOAM name |
|---|---|---|
| PRESSURE | 1 | p |
| MOMENTUM | 2 | U |
| TEMPERATURE | 3 | T |
| ENTHALPY | 4 | h |
| TKE | 5 | k |
| TED | 6 | epsilon |
| SPECIES | 7 | — |
| G | 8 | — |
| XF_RF_DATA_VOF | 150 | gamma |
| TOTAL_PRESSURE | 192 | — |
| TOTAL_TEMPERATURE | 193 | — |
意外と少ないなと思った人はいると思う。実際には記載の項目以外も設定できるのでそのリストを探しに行く。
#対応表の場所
OpenFOAM Advent Calendar 2017 2日目記事の方法でfoamDataToFluentのフォルダを探しに行く。今回はユーティリティなので、$FOAM_UTILITIESを探す。
$ find $FOAM_UTILITIES | grep "foamDataToFluent"

で、見つかったデータを眺めると、fluentUnitNumbers.txtなるものがあることが分かる。開いてみるとFluentのUnit Numberの対比表になっている。

#まとめ
OpenFOAMのユーザーマニュアルはリファレンスではないので、すべてがすべて網羅され、記述されているわけではない。
ソースコードの場所なども見る必要がある。
乱流モデルなどは参考文献や処理の考え方が書いてあったりするので、ネットで情報を探すのもいいが、ソースコードを見に行く癖はつけておきたいところ。
