ERROR #002100013 has occurred in subroutine Chk_Splane.          |

| The symmetry boundary condition requires that the boundary patch |
| mesh faces form a plane or axis.  However, face set  25 in the    |
| symmetry boundary patch                                           |
|                                                                   |

| 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.

【答案】應助回帖

我也遇到類似的問題，我直接按提示做，修改degeneracy check tolerance為1e-10，vector parallel tolerance為100之后，就能工作了。但計算太慢了，你又跟好的方法沒？

贊一下
