FLUENT中设置周期性边界条件的问题

herorongrui

我在做fluent一截管道的顺流模拟，进出口需要设为一组周期性边界条件，我在GAMBIT中进行了face mesh link，但在fluent中设置时失败了，进出口网格数一样啊，也是对应的，请问什么原因？
/grid/modify-zones> make-periodic
Periodic zone [()] wall.11
Shadow zone [()] wall.10
Rotational periodic? (if no, translational) [yes] no
Create periodic zones? [yes] yes
Auto detect translation vector? [yes] yes

  computed translation deltas: 0.000000 0.000000 -0.003999
  zone 3: matched 0 out of 11940 faces.
  zone 4: matched 0 out of 11940 faces.

Error: Failed to make zones periodic.
Error Object: #f

用gambit，直接把两组面指定到一个periodic边界条件组里面。
