@东岳 把网格加密后80*80算到time=0.05时就显示

浮点数例外 (核心已转储)

该怎么解决呢

按照文献中的案例模拟了一个三维方腔流
我的垂直速度曲线图和水平速度曲线图

和实验结果不一样

是什么原因造成的？

我想把数据导出来画速度分量时间平均分布

在pimpleFoam中算例的后台阶，请问一下，openfoam案例里面二维后台阶模型改成三维是不是只要把边界条件和blockMeshDict改一下就可以了

@东岳 在编译openfoam6时是输入./Allwmake进行编译，此时终端会输出：

Allwmake /home/zcy/OpenFOAM/OpenFOAM-6
gcc -m64 -Dlinux64 -DWM_ARCH_OPTION=64 -DWM_DP -DWM_LABEL_SIZE=32 -Wall -O3   -fPIC dirToString.c -o /home/zcy/OpenFOAM/OpenFOAM-6/wmake/platforms/linux64Gcc/dirToString

     static int input  (void)
                ^
Allwmake: no ThirdParty directory found - skipping
Allwmake src

这个时候dirToString和wmkdep应该已经编译好了，我想知道能不能在编译而不是复制这两个，给上Allwmake脚本内容

#!/bin/sh
cd ${0%/*} || exit 1    # Run from this directory

# Parse arguments for library compilation
. wmake/scripts/AllwmakeParseArguments
# Perform various checks
wmakeCheckPwd "$WM_PROJECT_DIR" || {
    echo "Allwmake error: Current directory is not \$WM_PROJECT_DIR"
    echo "    The environment variables are inconsistent with the installation."
    echo "    Check the OpenFOAM entries in your dot-files and source them."
    exit 1
}

[ -n "$FOAM_EXT_LIBBIN" ] || {
    echo "Allwmake error: FOAM_EXT_LIBBIN not set"
    echo "    Check the OpenFOAM entries in your dot-files and source them."
    exit 1
}

# Compile wmake support applications
(cd wmake/src && make)

# Compile ThirdParty libraries and applications
if [ -d "$WM_THIRD_PARTY_DIR" ]
then
    $WM_THIRD_PARTY_DIR/Allwmake
else
    echo "Allwmake: no ThirdParty directory found - skipping"
fi

路径是home/zcy/OpenFOAM/OpenFOAM-6/wmake/platforms/linux64Gcc
在其他虚拟机中OpenFOAM显示的样子

@星星星星晴 pisoFoam

@东岳 我做一个简单的渠道流，

U:
internalField   uniform (0.0335 0 0);

boundaryField
{
    IN
   {
        type            fixedValue;
        value           uniform (10 0 0);
    }

    OUT
    {
        type            zeroGradient;
    }


    WALL
    {
        type           noSlip;
    }


}
P:
dimensions      [0 2 -2 0 0 0 0];

internalField   uniform 0;

boundaryField
{
    IN
    {
        type            zeroGradient;
    }

    OUT
    {
        type            fixedValue;
        value           uniform 0;
    }

     WALL
    {
        type            zeroGradient;
    }

}

没有发现错误

运算时报错，应该怎么修改呢

--> FOAM FATAL ERROR:

我在controlDict里面出现添加了#includeFunc mag(U)
用pisoFoam运行后输入postProcess -func "mag(U)"，出现

functionObjects::mag mag(U) cannot find required object U of type volScalarField

这该怎么解决

@东岳 成功了，谢谢东岳老师了

我将算例cavity网格（20 20 1）变为（20 20 20）的情况icoFoam会算不出来

这是我的options：

EXE_INC = \
    
    -I$(LIB_SRC)/finiteVolume/lnInclude \
    -I$(LIB_SRC)/meshTools/lnInclude

EXE_LIBS = \
    -L</home/zcy/OpenFOAM/zcy-6/platforms/linux64GccDPInt32Opt/lib> \
    -l<myfiniteVolume> \
    -lmeshTools

我用wmake编译时生成文件Make/linux64GccDPInt32Opt时出现

Make/linux64GccDPInt32Opt/options:55: *** missing separator。

停止。
请问我该怎么修改呢

我自己编写了一个小型数据库fin，里面有cfdTools finiteVolume fvMesh lnInclude surfaceMesh fields fvMatrices interpolation Make volMesh。其中wmake文件最后一句写成LIB = $(FOAM_USUER_LIBBIN)/libmyfiniteVolume，现在我想把库链接到icoFoam
中，请问他的options我该怎么修改呢
icoFoam的options文件
EXE_INC =
-I$(LIB_SRC)/finiteVolume/lnInclude
-I$(LIB_SRC)/meshTools/lnInclude

EXE_LIBS =
-lfiniteVolume
-lmeshTools

@sibo fin文件里面有一个lnInclude文件，不是在finiteVolume中

EXE_INC = \
    -I$/home/zcy/openfoam/fin/lnInclude \
    -I$(LIB_SRC)/meshTools/lnInclude
EXE_LIBS = \
    -lmyfiniteVolume \
    -lmeshTools

这是我的InInclude
