想請問一下，在OpenFoam1712版本中tutorials/multiphase/interFoam/RAS/waterChannel/0文件里面的s字典是是什么物理量？我想計算波浪問題，加入kwsst模型，s字典有什么影響嗎？對于規則波一般在多少秒才能達到穩定？我閱讀別人的文獻一般只在30+s就穩定，我計算的要達到80+秒才穩定。

http://ihfoam.ihcantabria.com/source-download/     ihfoam官網，官網中寫道下面這一段話

As The Environmental Hydraulics Institute IHCantabria is an official contributions to OpenFOAM-v1612+  and OpenFOAM-1706, IHFOAM has become a part of the official release by OpenCFD (http://www.openfoam.com/). Therefore, once you download and install OpenFOAM in your computer, you will find the boundaries conditions and some tutorials.

在網上有人說openfoam1712版本中已經嵌入ihfoam模塊，但是我在該版本中沒有找到相對應的算例及相關內容？想請問一下具體是怎么回事
