一个2D的算例更好。可以调节进口速度，来测试是否是正常的。
1D算例由于通量守恒，不好测试

估计你下载的不是v11的版本。你要卸载互相适配的版本。

哥们有结果没，我最近也要使用这个求解器

@cccrrryyy 老师，想请教一下，如果对于mixtureKEpsilon这种两相都需要给个湍流模型初始值的该怎么弄呢？有k.air, k.water, km。。。之前估单相的用这个还没啥问题，现在上两相不知道咋整了:135:

屌爆了老铁，聊天记录已收藏，明天就发JFM

constrainPressure主要是更新压力第二类边界条件，公式如下：

\begin{equation}
\left( \nabla p_{rgh} \right)_f \cdot\bfn_f=
\frac{\left(\mathbf{HbyA}_f^{*}- \frac{1}{{{A^n_{\mathrm{P},f}}}}(\bfg\cdot\bfh\nabla\rho)_f - \mathbf{U}_f \right)\cdot\bfS_f}
{
|\bfS_f|
\frac{1}{{{A^n_{\mathrm{P},f}}}}
}
\end{equation}
上述公式与代码并不一致。在OpenFOAM中，constrainPressure为

forAll(pBf, patchi) { if (isA<fixedFluxPressureFvPatchScalarField>(pBf[patchi])) { refCast<fixedFluxPressureFvPatchScalarField> ( pBf[patchi] ).updateCoeffs ( ( phiHbyABf[patchi] - rho.boundaryField()[patchi] *MRF.relative(SfBf[patchi] & UBf[patchi], patchi) ) /(magSfBf[patchi]*rhorAUBf[patchi]) ); } }

多乘了一个密度。应该改为：

forAll(pBf, patchi) { if (isA<fixedFluxPressureFvPatchScalarField>(pBf[patchi])) { refCast<fixedFluxPressureFvPatchScalarField> ( pBf[patchi] ).updateCoeffs ( ( phiHbyABf[patchi] - MRF.relative(SfBf[patchi] & UBf[patchi], patchi) ) /(magSfBf[patchi]*rhorAUBf[patchi]/rho.boundaryField()[patchi]) ); } }

在非常老的OpenFOAM版本中，看起来是正确的，与公式一致

setSnGrad<fixedFluxPressureFvPatchScalarField> ( p_rgh.boundaryField(), ( phiHbyA.boundaryField() - fvOptions.relative(mesh.Sf().boundaryField() & U.boundaryField()) )/(mesh.magSf().boundaryField()*rAUf.boundaryField()) );

@yzwang 直接toposet就行，然后进行积分

@xuqiming 噢噢，这个问题解决了，需要厚度刚好覆盖这一层网格。

可以试试看symmetry边界

@李东岳 老师，我试过了，还是发散的，但是换更高质量的网格也可以收敛，（不收敛的网格icem中的quality为0.6，收敛的为0.75）这种情况是不是应该去尝试找一些新的收敛性更好的算法来实现呢

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

@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...
