ansys中如何把2个实体连接在一起？

可否实现一个面上的节点映射到另一面上使其成为另一面上的节点？

我想这样是否可行: 先把一个划分网格，再将交界面上的节点映射到另一个体表面，对另一个体划分网格，用merge命令把交界面上的节点合并。

可否在建模时候相连接部分都多出一些，然后使用add命令进行布尔操作，这样有了公共节点就好办一些

如果单纯就是这个模型，能不能换一种思路，先在UG或者CATIA中把面接好再做分析，作图形ansys不是强项

Element Connectivity Error, 8-Node Curved Shell Elements
In this image, the red stiffener was intended to be welded to the purple pipe. Note that the elements of the red stiffener do not match up with those on the pipe. There is no connection, and the meshing was done independently. This is due to a geometric modeling error by the user (me). There are superimposed curved lines where the interface is located. There should have been a shared line for the connection to have worked. I found this only because of careful examination of the model -- I had already run a stress analysis.
What to do about these error concerns? Read and think. Share and listen to ideas and concerns with others. Review your own work, and the work of your co-workers. (Recently an experienced co-worker who does not even do FEA work asked me if I had eliminated the added mass of water in pipes when evaluating shipping loads on a product. I hadn't. Eliminating the added mass got rid of a high-stress problem. These errors are very easy to make.) Be friendly. Communicate with other departments. Have a check list and design reviews. Never use FEA blindly, or believe the results of an analysis without some critical review. Accept a critical review without taking it personally. Develop a good understanding of the intent of the design codes that regulate your work. Consult an expert when it is appropriate. Pay attention to the ethics and standards of your professional association. Choose your employer wisely. (Some of these things you were supposed to have learned in Kindergarten, but life isn't always that simple.)
解决方法：通过volumn建模形成相贯线，该方法建模使面相交处共线，xmesh后有公共nodes

果然是两个曲面相连。
这个我也不会。关注答案
可以加个转接板麽？
