安装 geometricVofExt，遇到CGAL的链接和指向问题。

问题语句为 include $(GENERAL_RULES)/CGAL

请大佬指点一下，如何解决？！

安装过程如下：

CGAL 安装
安装后，检查是否安装成功： ****************************** Check CGAL ****************************** cgal=true flavour=library root="/home/ABCD/OpenFOAM/ThirdParty-v2506/platforms/linux64Gcc/CGAL-4.14.3" include="/home/ABCD/OpenFOAM/ThirdParty-v2506/platforms/linux64Gcc/CGAL-4.14.3/include" library="/home/ABCD/OpenFOAM/ThirdParty-v2506/platforms/linux64Gcc/CGAL-4.14.3/lib64" ********************************* Done *********************************

其中，ABCD表示 home 目录。

src/CGALVof 目录编译: 使用原始的 options 文件

无法编译 libCGALVof.so

>> wmake libso CGALVof make: *** /home/ABCD/OpenFOAM/OpenFOAM-v2506/wmake/rules/General/CGAL: Is a directory. Stop. make: *** /home/ABCD/OpenFOAM/OpenFOAM-v2506/wmake/rules/General/CGAL: Is a directory. Stop. wmake error: file 'Make/linux64GccDPInt32Opt/sourceFiles' could not be created in /home/ABCD/OpenFOAM/ABCD-v2506/modules/geometricVofExt/src/CGALVof

其中，原始 options 文件为

CGAL_EXACT = /*-DCGAL_DONT_USE_LAZY_KERNEL*/ CGAL_INEXACT = -DCGAL_INEXACT include $(GENERAL_RULES)/CGAL c++CGALWARN = -Wno-old-style-cast EXE_INC = \ -I$(LIB_SRC)/finiteVolume/lnInclude \ -I$(LIB_SRC)/fileFormats/lnInclude \ -I$(LIB_SRC)/surfMesh/lnInclude \ -I$(LIB_SRC)/dynamicFvMesh/lnInclude \ -I$(LIB_SRC)/meshTools/lnInclude \ -I$(LIB_SRC)/surfMesh/lnInclude \ -ICGALVof/lnInclude \ ${CGAL_EXACT} \ ${CGAL_INEXACT} \ ${CGAL_INC} \ ${c++CGALWARN} \ -fopenmp \ -frounding-math EXE_LIBS = \ ${CGAL_LIBS} \ -lfiniteVolume \ -lfileFormats \ -lsurfMesh \ -ldynamicFvMesh \ -lmeshTools

**根据错误提示，定位问题出在语句 include $(GENERAL_RULES)/CGAL **.

src/CGALVof 目录编译: 编译前导入环境变量

注释 options 文件中的语句 /*include $(GENERAL_RULES)/CGAL*/ **.

编译前导入的环境变量为

#!/bin/bash export CGAL_INC=-I${WM_THIRD_PARTY_DIR}/platforms/linux64Gcc/CGAL-4.14.3/include export CGAL_LIBS=-L${WM_THIRD_PARTY_DIR}/platforms/linux64Gcc/CGAL-4.14.3/lib64

编译命令为

source bashrc # bashrc 文件即为导入的环境变量 wclean wmake

成功编译出 libCGALVof.so

applications/utilities/setVofField 编译

根据第 3 步的经验，注释 options 文件中的语句 /*include $(GENERAL_RULES)/CGAL*/ **.

编译结果为

setShapedFields 的编译错误与上面的类似。

buoyantBoussinesqSimpleFoam10-12.tar.xz

这个压缩包里面有两个笨笨的求解器，分别适用于

OpenFOAM-10 OpenFOAM-12 （模块化）

算法主要基于老版本的buoyantBoussinesqSimpleFoam。这个求解器不需要求解能量方程，同时将动量方程处理为不可压缩。求解器稳定的多，不会出现负温度。但是在OpenFOAM-7之后被删掉了。

压缩包里面同时含有1个测试算例，分别适用于两个版本的求解器。对模块化求解器感兴趣的可以研究研究。我在植入过程中，模块化求解器的植入相对麻烦，主要是成员函数比较分散。OpenFOAM-10作为一个顶层的求解器在写的时候一气呵成。二者体验还是挺大的。

如果想在OpenFOAM-12里面植入求解器，可以对比下我写的求解器在10下以及12下的区别。

@李东岳 是的，李老师理解的没有错，就是高速可压缩反应流，爆轰就是激波和火焰面的耦合

@studentTan nCellsBetweenLevels 过渡层设置多一点，试下10层或20层

nCellsBetweenLevels 1;

画成一个平的圆形就行

这问题老大难了，基本要一事一议

有什么好的方法展示粒子的运动轨迹吗？

大家好
我想在SOWFA模拟过程中让风力机偏航角度随时间变化（动态偏航），请问有什么方法可以实现吗？我看SOWFA里面的偏航角设置是一个定值。

当时可真能写...

哎呀我勒个去 当时自己可真能写 现在看了都想删了 不嫌害臊

@xpqiu 哈哈哈必应第二条就是，谢谢邱老师！faf5e653-d711-4b05-aa92-a1af89def6f5-image.png

@李东岳 电流密度达到一定强度后表面会电离发射等离子体，我这里当气体模拟的

@capillaryFix 是的，我求解了Eqn.30 -> Eqn.34 ->Eqn.33，但是Eqn.33的结果用在哪里了？

@李东岳 在 如何根据stl模型定义cellZone？ 中说：

你需要看cellZone，不是看stl。paraFoam可以打开cellZone

老师，之前尝试过了，在一个snappyhexmeshdict中好像没有办法同时生成壁面边界模型和cellzone（即A.stl生成壁面模型，B.stl为cellzone区域），这个我在polymesh文件夹中检查了cellzone文件，的确为空。不过，后续我通过两次运行snappyhexmesh解决了，第一次只配置壁面边界模型，第二次只生成cellzone。

@xuluxi18 才看见，rhoCentralFoam能跑通，rhoPimpleFoam跑不通么

@chon01 这也只是我的猜测，因为我按了一下计算器，lg和ln函数算出来的结果差距确实比较明显，希望能帮到你吧。

@欧阳 我也尝试了一下，目前编译没啥问题

压力是没下去。原因不知道了，需要详细debug

搞出来了，一个小bug卡2小时
