为了验证 ParaView 输出结果的插件（如 PVblockMeshReader_SM 和 PVFoamReader_SM）是否成功安装，可以按照以下步骤操作：

检查插件库文件

确保生成的共享库文件存在于指定目录中：

ls /home/ovo/OpenFOAM/OpenFOAM-10/platforms/linux64GccDPInt32Opt/lib/paraview-5.6/

应该看到类似以下内容的输出：

配置 ParaView 环境变量

为了确保 ParaView 可以找到这些插件，您需要将插件目录添加到环境变量中。编辑 ~/.bashrc 文件并添加以下内容：

export PV_PLUGIN_PATH=/home/ovo/OpenFOAM/OpenFOAM-10/platforms/linux64GccDPInt32Opt/lib/paraview-5.6/

然后，运行以下命令使配置生效：

source ~/.bashrc

编译后的结果为:

以上文件目录中 /home/ovo/OpenFOAM/ThirdParty-10/build/linux64Gcc/ParaView-5.6.3/bin 下，有一些文件和目录，这些文件通常是 ParaView 编译后生成的可执行文件、配置文件以及相关工具和示例程序。让我来解释一下这些文件和目录的含义：

解释编译结果：
paraview:
这是 ParaView 的主要可执行文件。通过运行 ./paraview 或者 /home/ovo/OpenFOAM/ThirdParty-10/build/linux64Gcc/ParaView-5.6.3/bin/paraview 可以启动 ParaView 图形用户界面 (GUI)。
paraview-config:
这是用于配置和查询 ParaView 编译信息的工具。通常用于编译和链接外部程序与 ParaView 的集成。
pvdataserver:
这是 ParaView 的数据服务器可执行文件，用于在分布式计算中作为数据服务器运行。
pvrenderserver:
这是 ParaView 的渲染服务器可执行文件，用于在分布式计算中作为渲染服务器运行。
smTestDriver:
这是 ParaView 的测试驱动程序，用于执行和管理测试套件。
TestingDemo:
这是一个演示程序，用于展示 ParaView 的功能和特性。
vtk 开头的文件和目录：

这些文件是 ParaView 使用的 VTK（Visualization Toolkit）库的一部分，包括一些辅助工具和初始化脚本。

启动 ParaView 并检查插件

启动 ParaView命令：

paraview

或者使用完整路径启动:

/home/ovo/OpenFOAM/ThirdParty-10/build/linux64Gcc/ParaView-5.6.3/bin/paraview

在这里插入图片描述

在 ParaView 中，按照以下步骤检查插件是否加载成功：

打开插件管理器：
在菜单栏中选择 Tools -> Manage Plugins。
查找插件：(也就是确认OpenFOAM插件是否默认填入)
在插件列表中查找 PVblockMeshReader_SM 和 PVFoamReader_SM。如果它们显示在列表中并标记为已加载（Loaded），则表示插件安装成功。

加载插件：
如果插件没有自动加载，您可以手动选择插件并点击 Load Selected 按钮。

3.可视化测试插件功能

为了进一步验证插件的功能，您可以使用 OpenFOAM 提供的示例数据进行测试。以下是一个简单的测试步骤：

生成 OpenFOAM 示例数据：

cp -r $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity $FOAM_RUN
cd $FOAM_RUN/cavity
blockMesh
icoFoam

具体细节如下:
在这里插入图片描述

步骤一：复制案例文件

(py36) ovo@OVO:~/OpenFOAM/mycfd$ cp -r $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity $FOAM_RUN

命令解析：

cp -r: 复制命令，-r 选项表示递归复制，用于复制整个目录及其内容。
$FOAM_TUTORIALS: 这是一个环境变量，指向 OpenFOAM 的安装路径中的教程示例文件夹。
$FOAM_RUN: 这也是一个环境变量，指向 OpenFOAM 运行目录，通常用于存放用户自定义的仿真案例。
操作效果：

您在当前路径 ~/OpenFOAM/mycfd 下复制了 $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity 目录及其内容到 $FOAM_RUN 目录中。
如果复制成功，您现在的 $FOAM_RUN 目录中应该有一个名为 cavity 的目录，包含仿真案例所需的文件和子目录（0, constant, system）。

步骤二：查看目录内容

(py36) ovo@OVO:~/OpenFOAM/mycfd$ ls

这个命令在 ~/OpenFOAM/mycfd 目录下列出当前的文件和目录。
如果在这个目录中没有任何内容显示，可能是因为复制操作并未成功或者目录是空的。

步骤三：切换到教程示例目录

(py36) ovo@OVO:~/OpenFOAM/mycfd$ cd $FOAM_TUTORIALS

这个命令将当前工作目录切换到 $FOAM_TUTORIALS 环境变量指向的路径。
您在进入该目录后可以查看和访问 OpenFOAM 提供的各种教程示例。

步骤四：查看示例教程目录内容

(py36) ovo@OVO:~/OpenFOAM/OpenFOAM-10/tutorials$ ls

这个命令在 $FOAM_TUTORIALS 目录下列出了所有可用的教程示例。
列出的内容包括不同类型的流体动力学模型（如不可压缩流体、可压缩流体等）、离散方法、电磁学、热传递等。

步骤五：切换到运行目录

(py36) ovo@OVO:~/OpenFOAM/OpenFOAM-10/tutorials$ cd $FOAM_RUN

这个命令将当前工作目录切换到 $FOAM_RUN 环境变量指向的路径。
$FOAM_RUN 目录通常用于用户自定义的仿真案例和实验。

步骤六：查看运行目录内容

(py36) ovo@OVO:~/OpenFOAM/ovo-10/run$ ls

这个命令在 $FOAM_RUN 目录下列出当前的文件和目录。
如果输出中有 cavity 目录，则表示 cavity 目录已经成功地复制到了 $FOAM_RUN 目录中。
步骤七：进入复制后的案例目录

(py36) ovo@OVO:~/OpenFOAM/ovo-10/run$ cd $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity

这个命令将当前工作目录切换到 $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity 目录。
这是仿真案例 cavity 的实际存放位置，包含了仿真所需的 0, constant, system 子目录。

3.加载数据进行可视化

在 ParaView 中加载数据：

在 ParaView 中，选择 File -> Open，然后导航到 cavity 目录，打开生成的 cavity.OpenFOAM 文件。

查看结果：ParaView 应该可以正确读取并显示模拟结果。

具体细节如下:

第一步: 导入案例

先创建项目:

mkdir -p $FOAM_RUN
cd $FOAM_RUN

导入案例:
cp -r $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity $FOAM_RUN
在里插入图片描述

第二步:查看当前目录未更新前的内容

/home/ovo/OpenFOAM/ovo-10/run/cavity
在这里插入图片描述
以上这个目录结构是一个典型的 OpenFOAM 仿真案例的组织形式，主要用于模拟流体力学问题。让我来解释每个文件和文件夹的内容：

目录结构说明：

0/
p: 存储压力场数据文件。

U: 存储速度场数据文件。

这些文件是仿真运行后生成的时间步结果。在每个时间步结束时，OpenFOAM 将当前时间步的压力和速度场数据分别保存在 p 和 U 文件中。

constant/
physicalProperties: 定义了仿真中使用的物理属性的文件。

在这个文件中，您会找到描述流体密度、动力粘度等参数的设定。这些参数对于定义仿真所用的流体的基本特性至关重要。

system/
blockMeshDict: 网格生成器的设置文件，用于定义仿真区域的几何形状和网格划分。

这个文件包含了关于如何生成仿真所需网格的具体指令，包括顶点坐标、网格块（blocks）的定义以及边界（boundaries）的设置。

controlDict: 控制求解器行为和参数的主要设置文件。

controlDict 文件定义了如何运行仿真，包括开始时间、结束时间、时间步长、输出控制等参数。它是控制整个仿真过程的关键文件。

fvSchemes: 定义了数值离散格式的文件。

在这个文件中，您可以设置用于空间离散（如对流项和扩散项）和时间离散的数值格式。这些设置直接影响仿真的数值精度和稳定性。

fvSolution: 定义了求解器的设置文件。

fvSolution 文件包含了定义压力速度耦合算法、求解器迭代次数、收敛准则等设置。它对于确定仿真如何收敛到稳态或者如何在时间上推进至关重要。

以上文件和文件夹构成了一个完整的 OpenFOAM 仿真案例的基本组成部分。每个文件都承担着定义和控制仿真不同方面的重要角色，从网格生成到物理特性的设定，再到数值方法和求解器的选择和配置。理解和正确设置这些文件是进行 OpenFOAM 模拟的关键步骤，能够帮助您成功地执行流体力学仿真并进行后处理分析。

第三步:使用 blockMesh 命令生成腔体案例的网格

在这里插入图片描述
查看生成的新文件:

生成新的文件说明：

blockMeshDict：网格生成器的设置文件，用于定义仿真区域的几何形状和网格划分方式。这个文件由 blockMesh 程序使用，生成仿真所需的数值网格。

controlDict：控制字典文件，定义了求解器的运行控制参数，例如仿真的时间步长、总仿真时间、数据输出频率等。这些参数直接影响到仿真过程的进行和结果的生成。

fvSchemes：数值格式方案文件，用于定义仿真中所采用的数值离散格式，包括对流项、扩散项等的数值计算格式及其参数设置。

fvSolution：求解方案文件，定义了求解器的具体设置和算法选择，例如压力速度耦合算法的选择、迭代收敛准则等。这些设置直接影响到仿真求解器的稳定性和精度。

以上文件夹和文件组成了一个完整的 OpenFOAM 仿真案例（case），其中包含了仿真所需的初步网格定义、物理属性设定、数值格式方案和求解器参数设置。通过这些文件，OpenFOAM 可以进行数值流体力学仿真，并生成压力场和速度场等数据文件，供后续的分析和可视化使用。

第四步:运行仿真icoFoam

icoFoam这个命令会启动 icoFoam 求解器，适用于不可压缩、层流流动的仿真。

使用 icoFoam 求解器运行仿真,输出仿真结果如下:

仿真之后的文件变化如下:
在这里插入图片描述
在 OpenFOAM 的仿真过程中，随着时间步的推进，会生成多个时间目录（例如 0, 0.1, 0.2 等），每个时间目录都包含了仿真在不同时间步长下的数据文件。以下是每个目录的详细解释：

时间步目录 (0, 0.1, 0.2, …)
目录结构：

0, 0.1, 0.2, 0.3, 0.4, 0.5, ...
├── p
├── phi
├── U
└── uniform└── time

说明：

p：压力场的数据文件，在每个时间步下记录了仿真区域内各个点的压力值。
U：速度场的数据文件，在每个时间步下记录了仿真区域内各个点的速度向量。
phi：如果在仿真过程中有其他需要求解的场变量（如浓度场等），会有对应的 phi 文件。
uniform/time：这个目录存放着与时间相关的统一数据，通常包括时间步长和仿真开始时间等信息。

时间步结果

Time = 0.005sCourant Number mean: 0 max: 0
smoothSolver:  Solving for Ux, Initial residual = 1, Final residual = 8.90511e-06, No Iterations 19
smoothSolver:  Solving for Uy, Initial residual = 0, Final residual = 0, No Iterations 0
DICPCG:  Solving for p, Initial residual = 1, Final residual = 0.0492854, No Iterations 12
time step continuity errors : sum local = 0.000466513, global = -1.79995e-19, cumulative = -1.79995e-19
DICPCG:  Solving for p, Initial residual = 0.590864, Final residual = 2.65225e-07, No Iterations 35
time step continuity errors : sum local = 2.74685e-09, global = -2.6445e-19, cumulative = -4.44444e-19
ExecutionTime = 0.024026 s  ClockTime = 0 s

这些行显示了每个时间步的仿真结果和求解器运行信息：

Time = 0.005s：当前时间步的时间。
Courant Number：库朗数的平均值和最大值。
smoothSolver 和 DICPCG：分别表示速度场 (Ux, Uy) 和压力场 (p) 的求解过程，包括初始残差、最终残差、迭代次数等信息。
time step continuity errors：时间步连续性误差的局部和全局汇总。
ExecutionTime 和 ClockTime：仿真程序的执行时间和实际时钟时间。

以上的这些信息记录了 OpenFOAM 仿真过程中的关键步骤和详细数据，帮助用户了解仿真的进行情况、求解器的性能表现以及时间步的数值稳定性。通过分析这些输出，可以评估仿真的收敛性和准确性，进而调整参数或改进模型以获得更好的仿真结果。

第五步:使用 ParaView 进行后处理

仿真完成后，使用 ParaView 打开结果进行可视化和后处理：

paraFoam

在这里插入图片描述

这个命令会将仿真结果加载到 ParaView 中，您可以在其中查看压力 § 和速度 (U) 等场变量，应用滤波器，并分析仿真输出。

注意事项：
文件位置：确保您的环境变量如 $FOAM_TUTORIALS 和 $FOAM_RUN 在 OpenFOAM 设置脚本中正确设置（如 $HOME/OpenFOAM/OpenFOAM-9/etc/bashrc 或类似文件）。
理解腔体案例：腔体教程案例 (cavity) 模拟了一个正方形腔体内部的流动，设定了特定的边界条件，是学习 OpenFOAM 基础知识的理想案例。
