CFL3D

CFL3D is a structured-grid, cell-centered, upwind-biased, Reynolds-averaged Navier-Stokes (RANS) code. It can be run in parallel on multiple grid zones with point-matched, patched, overset, or embedded connectivities. Both multigrid and mesh sequencing are available in time-accurate or steady-state modes.

编译说明

Linux

• 编译工具
  • CMake >= 3.13
  • Intel oneAPI Base Toolkits
  • MPI库用于编译并行版本，已测试
    • Intel MPI (oneAPI HPC Toolkits)
    • MPICH
• 编译步骤

  cd CFL3D
  mkdir build && cd build
  FC=ifort CC=icc CXX=icpc cmake ..
  make -j
  make install

• CMake选项
  • -DCMAKE_BUILD_TYPE=[Release]|Debug|...：编译类型
  • -DCMAKE_INSTALL_PREFIX=/path/to/install：CFL3D的安装路径
  • -DSINGLE_PRECISION=ON|[OFF]：编译单/双精度版本，默认双精度
  • -DNO_REDIRECT=ON|[OFF]：采用cfl3d.inp作为输入文件，禁用管道重定向
  • -DWITH_FASTIO=[ON]|OFF：禁用并行输出
  • -DWITH_DELAUNAY=ON|[OFF]：编译Delaunay网格变形模块
  • -DHPC=ON == -DNO_REDIRECT=ON -DWITH_FASTIO=OFF
  • -DBUILD_*=ON|OFF：打开/关闭指定包的编译
    • SEQ 串行版本，[ON]
    • MPI 并行版本，[ON]
    • SPLITTER 分块工具，[ON]
    • PRECFL3D 输入检查，[ON]
    • RONNIE & PRERONNIE 搭接网格，[OFF]
    • MAGGIE 重叠网格，[OFF]
    • TOOLS 多种小工具，[ON]

Windows

可以通过WSL安装，参照Linux安装方法

特性

1. 默认ifullns = 1，在2D中务必手动置零
2. IDDES-SA 混合湍流模型
3. 湍流模型分支/修正
4. 收敛准则
5. 阵风模型
6. 非定常入口
7. 壁面喷流边界条件 (BC2036)
8. 基于Delaunay映射的网格变形

特别注意事项

1. 如果出现错误forrtl: severe (174)，说明栈空间溢出，执行 ulimit -s unlimited 以临时解除限制。管理员可以修改系统配置永久解除。
2. 由于CFL3D代码的BUG，Delaunay映射与Finite Macro Elemnt在大规模问题中无法使用。因此从性能角度出发默认关闭了WITH_DELAUNAY并开启全局链接优化，全局链接优化耗时很长，请耐心等待。
