[求助]SYM不是平行面设置的问题
我在做3D pipejunction 例题的时候画好了网格,前期准备工作按教程用ICEM CFD都完成了,自己想尝试用CFX试算,在计算中报错如下,请教各位大侠该如何解决?!!谢谢!!

| ERROR #002100013 has occurred in subroutine Chk_Splane. |
| Message: |
| The symmetry boundary condition requires that the boundary patch |

|SYM |
| |
| is not in a strict plane, which means that at least one of its |
| faces is not parallel to the others.To make the solver run |
| you can do one of the following: |
| |
|(1) Make sure that this symmetry boundary patch is in a plane or|
| axis by checking and regenerating the mesh. |
|(2) If the symmetry boundary patch is an axis rather than a |
| plane, change the tolerance of the degeneracy check by |
| increasing the value of the Solver Expert Parameter |
| ';degeneracy check tolerance'; (the default value is 1.e-4). |
|(3) Increase the value of the Solver Expert Parameter |
| ';vector parallel tolerance'; (the default value is 1 deg.). |
| Note that the accuracy of the symmetry condition may decrease |
| as the tolerance is increased.This is because the tolerance |
| is the number of degrees that a mesh face normal is allowed |
| to deviate from the average normal for the entire face set. |

不知道在哪里能找到';vector parallel tolerance'; 。[以下内容由 liangxia 在 2007年12月20日 05:51pm 时添加]

[求助]SYM不是平行面设置的问题
你可能在创建几何或划分网格时没注意,有的地方出现了误差,积累起来造成这个问题。你可以在CFX-POST中检查这个问题。
要设定';vector parallel tolerance'; 需要用到CFX的高级参数模式,GUI里是没有的。 要设定';vector parallel tolerance'; 需要用到CFX的高级参数模式,GUI里是没有的
有人说修改路径是
Create > expert objects>expert parameter > Discretisation ->last one
请问在哪里操作啊?一直没研究出来,遇到这个问题,解决不了 The symmetry boundary condition requires that the boundary patchmesh faces form a plane or axis.However, face set 7 in the symmetry boundary patch。我也遇到了这个问题,请问楼主是怎么解决的,谢谢啦
