我对使用讨论过的这里的开放源代码很感兴趣。讨论了如何运行代码的框架和一些说明，并对这里进行了讨论。要能够使用代码，首先应该安装PETSc。我已经这样做了，它似乎是正确的安装。当我按照make topopt中给出的指令运行纸时，问题就会出现(第2.2节)。在GitHub上存在一个makefile_ref，它按照纸中的指令进行以下更改：PETSC_DIR=\home\myusername\petsc和PETSC_ARCH=arch-linux-c-debug。在运行make -d topopt之后，我得到以下错误：

答案：

事实上，编译GitHub上给出的拓扑优化代码并不是那么复杂。在这里，我重申了已经给出的关于GitHub的说明，并给出了更多的细节。

要使用PETSc运行拓扑优化开源代码，首先需要安装PETSc。您应该注意，要安装PETSc，您需要安装BLAS和LAPACK库，它非常简单，并在PETSc中给出了说明。既然PETSc已经安装在系统上，就只需从GitHub克隆TopOpt_in_PETSc。

您将找到一个名为makefile_ref的文件，将该文件的名称更改为makefile，然后打开它，并在代码的前两行修改路径，这将类似于PETSC_DIR=/home/username/petsc和PETSC_ARCH=arch-linux-c-debug (在我的例子中是这样，根据您的计算机可能有所不同)。前者是在本地计算机上安装PETSc的目录的路径，后者是PETSc的构建名称。

一旦完成了上述操作，您就可以运行make topopt，它将构建一个名为topopt的可执行文件。按照纸中给出的指令，您将能够运行拓扑优化模拟。

备注:上面给出的安装说明是在ubuntu20.04LTS上执行的，尽管PETSc也兼容iOS和iOS，甚至是安卓。另一方面，TopOpt_in_PETSc是在linux上开发和实现的，很可能需要在linux上安装进一步的操作。

有一个makefile_ref，按照论文中的说明，我做了以下修改.

如果没有指定要读取的makefile的显式选项，make实用程序将通过几个替代名称查找输入文件。makefile_ref不是其中之一。我将文件名的"_ref“部分作为”引用“的助记符，从这个角度来看，您的意图似乎是将makefile_ref复制到makefile ( make默认需要的文件名之一)，并修改副本以适合您的环境。
