Compilation and Installation

Procedure

1. Use PuTTY to log in to the server as the root user.
2. Go to the OpenFOAM installation package directory.

   cd /path/to/OpenFOAM

3. Decompress the OpenFOAM installation package.

   tar -xvf OpenFOAM-v1906.tgz
   tar -xvf ThirdParty-v1906.tgz

4. Go to the directory generated after the decompression.

   cd OpenFOAM-v1906

5. Create a List.H.patch file and edit it.
   1. Create a List.H.patch file.

      vi List.H.patch

   2. Press i to enter the insert mode and type the following content:

7. Apply the patch.

   patch -p1 < List.H.patch
   patch -p1 < IListStream.H.patch

8. Modify the compiler and MPI settings in the OpenFOAM installation configuration file.

   Change export WM_COMPILER=/path/to/clang to export WM_COMPILER=Clang.

   

   Change /path/to/clang to the clang file path of the BiSheng Compiler.

9. Modify the compilation parameters.

   sed -i 's/\-O3/\-O3 \-march=armv8-a/g' /path/to/OpenFOAM/OpenFOAM-v1906/wmake/rules/linuxARM64Clang/c++Opt
   sed -i 's/\-O3/\-O3 \-march=armv8-a/g' /path/to/OpenFOAM/OpenFOAM-v1906/wmake/rules/linuxARM64Clang/cOpt

10. Make the OpenFOAM configuration file bashrc take effect.

    source etc/bashrc

11. Perform the compilation and installation.

    ./Allwmake -j -k
