求助:我用cfx4.4遇到的一些困难（初学者）

平凡

   我在用cfx4.4建模时，网格画好后，分析时总是出现：The following errors were found during checking:
From number of quad4 elements on the faces of Solid 9 expect to find 378 nodes associated with those quad4 elements. However 426 nodes actually found - probably need to equivalence more nodes.
From number of quad4 elements on the faces of Solid 10 expect to find 426 nodes associated with those quad4 elements. However 448 nodes actually found - probably need to equivalence more nodes.
From number of quad4 elements on the faces of Solid 11 expect to find 954 nodes associated with those quad4 elements. However 1058 nodes actually found - probably need to equivalence more nodes.
From number of quad4 elements on the faces of Solid 12 expect to find 1038 nodes associated with those quad4 elements. However 1105 nodes actually found - probably need to equivalence more nodes.
From number of quad4 elements on the faces of Solid 13 expect to find 154 nodes associated with those quad4 elements. However 193 nodes actually found - probably need to equivalence more nodes.
From number of quad4 elements on the faces of Solid 14 expect to find 188 nodes associated with those quad4 elements. However 210 nodes actually found - probably need to equivalence more nodes.
From number of quad4 elements on the faces of Solid 18 expect to find 154 nodes associated with those quad4 elements. However 199 nodes actually found - probably need to equivalence more nodes.
From number of quad4 elements on the faces of Solid 19 expect to find 188 nodes associated with those quad4 elements. However 218 nodes actually found - probably need to equivalence more nodes.
  这样的错误，我是个初学者，我老师忙，没有时间指点我，就让我自学，我自己也试了很多，但是就是不知道为什么：我认为可能是画几何体时精确度的原因，或者是斜四面形网格有关。
  在这里请遇到过类似情况的前辈指点下，晚辈感激不尽！
