SonmiHPCOpenFoam 安装及使用
OpenFOAM 是对连续介质力学问题进行数值计算的 C++ 自由软件工具包，其代码遵守 GNU 通用公共许可证。它可进行数据预处理、后处理和自定义求解器，通常用于流体力学领域的计算。本教程将介绍如何在 SonmiHPC 集群上编译及安装 OpenFOAM。
安装依赖工具
编译安装 OpenFOAM 需要依赖下面的一些工具：
- GCC，集群中默认已集成 11.5版本
- CMake，参考安装文档
- OpenMPI，参考安装文档
系统还需额外安装如下的依赖库：
shell
dnf -y install git flex bison cmake zlib-devel zlib qt5-qtbase-devel openssl openssl-devel libXt-devel libX11-devel qt5-qtx11extras-devel qt5-qttools-develdnf -y install git flex bison cmake zlib-devel zlib qt5-qtbase-devel openssl openssl-devel libXt-devel libX11-devel qt5-qtx11extras-devel qt5-qttools-devel获取源码
直接将源码克隆到本地：
shell
cd /share/apps/
git clone --branch version-12 https://github.com/OpenFOAM/OpenFOAM-12.git
git clone --branch version-12 https://github.com/OpenFOAM/ThirdParty-12.gitcd /share/apps/
git clone --branch version-12 https://github.com/OpenFOAM/OpenFOAM-12.git
git clone --branch version-12 https://github.com/OpenFOAM/ThirdParty-12.git编译安装
加载环境变量及依赖的环境模块：
shell
source OpenFOAM-12/etc/bashrc
module load cmake/3.30.0
module load openmpi/5.0.3source OpenFOAM-12/etc/bashrc
module load cmake/3.30.0
module load openmpi/5.0.3注意，如果是使用 《Open MPI 安装及使用 》该教程安装的Open MPI版本，需要做一个软链接解决寻找mpi链接库报错问题：
shell
ln -s /share/apps/openmpi/5.0.3/lib /share/apps/openmpi/5.0.3/lib64ln -s /share/apps/openmpi/5.0.3/lib /share/apps/openmpi/5.0.3/lib64安装第三方组件：
shell
cd ThirdParty-12
./Allwmake
cd ../OpenFOAM-12
./Allwmake -q -j 8cd ThirdParty-12
./Allwmake
cd ../OpenFOAM-12
./Allwmake -q -j 8Modulefile 文件编写
编译好的程序可以通过 Module 模块的方式提供给集群上其他用户使用，可以编写如下的 Modulefile 文件，首先创建文件夹：
shell
mkdir -p /share/apps/modulefiles/openfoammkdir -p /share/apps/modulefiles/openfoam在该路径下创建modulefile文件：
shell
vim /share/apps/modulefiles/openfoam/12vim /share/apps/modulefiles/openfoam/12文件内容如下：
tcl
#%Module###########################################
set modulefilename "OpenFOAM"
set modulefilever "12"
set min_tcl_ver 8.4
if { $tcl_version < $min_tcl_ver } {
puts stderr " "
puts stderr "ERROR: This modulefile requires tcl $min_tcl_ver or greater."
puts stderr "Your system reports that tclsh version $tcl_version is installed."
exit 1
}
if { [ module-info mode load ] } {
puts stderr "Loading $modulefilename version $modulefilever"
}
if { [ module-info mode ] == "unload" || [ module-info mode ] == "remove" } {
puts stderr "Removing $modulefilename version $modulefilever"
puts stderr "Use to view any remaining dependent modules."
}
prereq openmpi/5.0.3
set root /share/apps/OpenFOAM-12
source-sh bash $root/etc/bashrc#%Module###########################################
set modulefilename "OpenFOAM"
set modulefilever "12"
set min_tcl_ver 8.4
if { $tcl_version < $min_tcl_ver } {
puts stderr " "
puts stderr "ERROR: This modulefile requires tcl $min_tcl_ver or greater."
puts stderr "Your system reports that tclsh version $tcl_version is installed."
exit 1
}
if { [ module-info mode load ] } {
puts stderr "Loading $modulefilename version $modulefilever"
}
if { [ module-info mode ] == "unload" || [ module-info mode ] == "remove" } {
puts stderr "Removing $modulefilename version $modulefilever"
puts stderr "Use to view any remaining dependent modules."
}
prereq openmpi/5.0.3
set root /share/apps/OpenFOAM-12
source-sh bash $root/etc/bashrc保存文件后，设置一下权限：
shell
chmod -R 755 /share/apps/modulefileschmod -R 755 /share/apps/modulefiles集群上面用户可以通过下面的命令来查看该模块：
shell
[sonmi@sonmi ~]$ module avail
------------------- /share/apps/modulefiles -------------------
openfoam/12[sonmi@sonmi ~]$ module avail
------------------- /share/apps/modulefiles -------------------
openfoam/12用户可以通过下面的命令来加载该模块：
shell
module load openfoam/12module load openfoam/12
