圆柱型流化床二维模型 模拟

流化床2D模拟，先是画了一个矩形，然后设置边界条件，进口inlet；出口outlet；其余为wall；计算提示如下错误：
| ERROR #002100048 has occurred in subroutine SU_BNEXT.              |
| Message:                                                           |
| All vertices for a fluid domain lie on boundaries.  This is        |
| considered to be a fatal error because control volume gradients    |
| cannot be calculated, leading to serious discretization error.     |
|                                                                    |
| A common cause for this error is a mesh which is only one          |
| element thick, without symmetry or 1:1 periodicity on the lateral  |
| boundaries.  If you have this situation, and the domain is         |
| two-dimensional, please change the lateral boundary conditions     |
| to symmetry or 1:1 periodicity.  Alternatively, for                |
| three-dimensional simulations, please ensure that your mesh        |
| has at least two elements across.           
貌似是要设置对称性边界条件，把除进口和出口外的所有面都设置成symmetry么？
