openfoam从9还是10开始，编译需要超大内存。那次大版本更新一堆编译爆了的。要么增加内存条或者swap，要么编译的时候不要直接 -j 用上所有的核，用少一些核，内存占用会降低，只是编译速度慢点。
可以编译的时候开着系统资源管理器看着内存占用，是不是到100%之后猛的下降。

UDF函数求助这些是内部函数，只有头文件里有声明。是常见的商业软件保密方法。（只发布头文件和源代码编译成的动态链接库）
如果要使用，
第一步，包含定义该函数的头文件
第二步，编译的时候链接到包含该函数定义的动态链接库。可以使用grep找到包含该函数的声明头文件和各状况下的动态链接库。

foam-extend-4.0 移植重叠网格 wmake编译报错@Gunther 已经include？你是说在源代码里写的包含头文件那句代码？
你知道那个文件在哪，但是gcc不知道，所以得在options里写明，头文件的位置，和库文件的位置。
头文件可以让gcc知道有哪些函数可用，头文件一般都是函数声明。库文件定义函数如何运行。所以位置都得指明。
那些个IDE有的设定好了，把这些细节藏起来了。
至于为什么你的options文件没有发挥作用，我看你也没把overset的头文件写进包含里呀，具体怎么写不知道，但大概应该像这个的最后一行，地址不一定对，那你觉得你之前的option文件里，第几行包含了overset的头文件呢？
EXE_INC = \ -I$(LIB_SRC)/finiteVolume/lnInclude \ -I$(LIB_SRC)/meshTools/lnInclude \ -I$(LIB_SRC)/surfMesh/lnInclude \ -I$(LIB_SRC)/sampling/lnInclude \ -I$(LIB_SRC)/lduSolvers/lnInclude \ -I$(LIB_SRC)/overset/lnInclude -

cellMotion边界条件源码阅读求助找pp[i].average的定义
pp是p的patch的引用，p是this的patch的引用。
所以pp是this的patch的patch。
所以pp的子函数average要从this里找。this就是当前这个类：cellMotionFvPatchField
这个类的定义在：
src/fvMotionSolver/fvPatchFields/derived/cellMotion/cellMotionFvPatchField.H由类定义可知，该类继承自 fixedValueFvPatchField.H (
src/finiteVolume/fields/fvPatchFields/basic/fixedValue/fixedValueFvPatchField.H)fixedValueFvPatchField 又继承自 fvPatchField (
src/finiteVolume/fields/fvPatchFields/fvPatchField/fvPatchField.H)
这里352行，有patch函数，返回值是patch_src/finiteVolume/fields/fvPatchFields/fvPatchField/fvPatchField.C中显示patch_的初始变量是fvPatch类型的(this的patch)src/finiteVolume/fvMesh/fvPatches/fvPatch/fvPatch.H
这里142行，有patch函数，返回值是polyPatch_，它的声明在69行，是polyPatch类型(this的patch的patch)polyPatch里没有average函数，接着往基类上找(
src/OpenFOAM/meshes/polyMesh/polyPatches/polyPatch/polyPatch.H)继承自两个类：patchIdentifier, primitivePatch
第一个查无所获，第二个：
src/OpenFOAM/meshes/primitiveMesh/primitivePatch/primitivePatch.H里面有四个头文件，一个个找过去，
第一个：
src/OpenFOAM/meshes/primitiveMesh/PrimitivePatch/PrimitivePatch.H（^处两个字母，大小写和上面不一样） ^ ^没有average函数
第二个：
src/OpenFOAM/meshes/meshShapes/face/face.H好了，找到函数原型：148行
//- Calculate average value at centroid of face template<class Type> Type average(const pointField&, const Field<Type>&) const;代码行数都是OpenFOAM 10版本的
网页搜着慢，可以自己编译个本地的，搜着快，一句命令就可以生成。

src命令直接跳到源代码目录，然后：直接找到类的定义：
find . -name calssWhatIWant.H直接找函数：
grep -r "functionWhatIWant(" .加半拉括号是为了减少搜索到的结果。搭配正则表达式用，搜的效率更高。
