分享一个在任意文件夹中编译库或求解器的办法

白礼耕

众所周知，OpenFOAM只允许用户把编译好的库（lib）和求解器（solver）放在 $FOAM_USER_APPBIN 或 $FOAM_APPBIN 文件夹中。

科研时间久了，某一个库经过太多次的修改，会有很多个不同版本的代码。如果需要使用其中的一个版本，就要重新编译。如果想同时保留两个版本的求解器，就只能在修改代码的过程中，精心安排每一个编译好的库的名字，比如把 Make/files 文件中的 libcombustionModels 命名为 libcombustionModelsNew libcombustionModelsNewNew…… 只有这样，才能保留不同求解器各自需要的库（.so）文件。改的库多了，工作量就会几何增长！（比如turbulenceModels 建立在thermophysicalModels的基础上，lagrangian 又基于湍流模型，每一个库里都有大量的lib，每一个修改过的lib都需要重新命名，牵一发动全身！如果改了fluidThermo，那简直是欲哭无泪）

网上好像还没有人讨论过这个问题。经过研究，终于找到了一个打破僵局的办法。实现一个新的算法，只需要把新代码放在一个文件夹下，所有库的名字都不用修改。新生成的库，都会以旧代码的库名字保存在新的文件夹下，只要solver中指定需要哪个文件夹下的库就好了。

首先打开terminal，进入到OpenFOAM的文件夹下

$cd $WM_PROJECT_DIR/etc/

在bashrc文件中添加一行代码（在terminal中输入以下代码）：

$sed -i '/WM_PROJECT_USER_DIR_DEV/iexport WM_PROJECT_USER_DIR_DEV=$HOME/$WM_PROJECT/$USER-$WM_PROJECT_VERSION-dev' bashrc

其中，WM_PROJECT_USER_DIR_DEV 是自己取的名字，$USER-$WM_PROJECT_VERSION-dev 是想要储存新代码和库的文件夹路径，这里是创建user-版本号-dev,和$FOAM_USER_APPBIN文件夹同级。

之后，

$cd $WM_PROJECT_DIR/etc/config
$sed -i '/FOAM_USER_LIBBIN/iexport WM_PROJECT_USER_DIR_DEV=$WM_PROJECT_USER_DIR_DEV/platforms/$WM_OPTIONS/lib' settings.sh
$sed -i -e 's=_foamAddLib  $FOAM_USER_LIBBIN\:=_foamAddLib  $FOAM_USER_LIBBIN_DEV:$FOAM_USER_LIBBIN=' settings.sh

完成在$FOAM_USER_LIBBIN这一行添加新的路径$FOAM_USER_LIBBIN_DEV，其位置在新代码所在的文件夹中。

之后，只要参照下面的命令批量替换新代码中Make/options和Make/files中OpenFOAM寻找库的路径，并保证求解器调用新路径下的库就好了！

sed -i "s/$(FOAM_USER_LIBBIN/$(FOAM_USER_LIBBIN_DEV/g" `grep "lib<自己命名的库>" -rl ~/OpenFOAM/user-版本号-dev/src`

我来分享一哈我的配置方法。总之就是把用户自定义的和官方的分开。省的乱了。至于命名，如果修改版本特别多，官方名加日期命名比较好。代码最好用版本管理器，还能加加些笔记标注每个版本做了什么修改，是从哪个版本来的。

是的，就是为了给用户自定义的文件更好分类。
我的方法是生成FOAM_USER_SRC_A，FOAM_USER_SRC_B，FOAM_USER_SRC_C，可以在每一个文件夹下各自存放自定义库和求解器，这样就避免了重命名或者版本管理。每一个SRC下的文件单独拖出来，都可以直接在cluster上编译运行
