在Fluent中采用TUI设置周期性边界的方法

By Zjz

(1) 首先，指定计算域的Rotational Axis(Cell Zone Conditions中，Frame Motion)

(2) 其次，对响应的组件进行周期性设置，命令为：

/mesh/modify-zones> make-periodic

Periodic zone 13

Shadow zone 14

Rotational periodic ? (if no, translational) y

Create periodic zones? y

zone 14 deleted

created periodic zones.

. The matching tolerance for a face is a fraction of the minimum edge length of the face. If the periodic boundary creation fails, you can change the matching tolerance using the mesh/modify-zones/matching-tolerance text command, but it should not exceed 0.5 or you may match up the periodic zones incorrectly and corrupt the mesh.)

(3) 然后，检查周期性边界条件是否设置成功(菜单栏：mesh/check)。周期边界设置失败时，Fluent提示：WARNING: rotation inconsistent on zone 9. Please check periodic setup.可以采用如下命令进行修正：

/mesh/repair-improve> repair-periodic

Repair rotational periodic angles? y

Periodic zone 13 is swapped

Periodic zone 14: average rotation angle (deg) = 5.455 (5.454 to 5.455)

stored zone rotation angle (deg) = 5.454

stored axis , (1.000000e+00, 0.000000e+00, 0.000000e+00) stored origin, (0.000000e+00, 0.000000e+00, 0.000000e+00) Periodic zone 9: average rotation angle (deg) = 4.736 (4.737 to 4.737)

stored zone rotation angle (deg) = 4.737

stored axis , (1.000000e+00, 0.000000e+00, 0.000000e+00) stored origin, (0.000000e+00, 0.000000e+00, 0.000000e+00)

(4) 至此，周期性边界设置完成，返回上一级命令(>quit或者>q)。
