手册中:关于设置动网格用一阶单元的那半句话。

在modeling.pdf中Limitations of the Deformed Mesh Feature，有这么一段关于设置deformed mesh为1阶单元的话：

When using second-order (or higher-order) elements in the deformed mesh application modes, the mesh moving techniques often produce elements with distorted shapes. The measure of mesh quality does not capture these distorted shapes because it is computed from the positions of the corners of the mesh element (ignoring mid-side nodes, for instance). For these reasons, it is often best to use linear elements for the mesh positions in the deformed mesh application modes. You can select element type on the Element tab in the Subdomain Settings dialog box for the Moving Mesh (ALE) and Parameterized Geometry application modes. You must also open the Model Settings dialog box from the Physics menu and select the ALE frame (typically Frame (ale)) in the Frames list and select the appropriate element order (typically Linear) in the Geometry shape order list.

好了，找个模型库中的例子试试吧！

你按照手册中的设置试试？ 看看会发什么？ 怎么办？ 呵呵，有兴趣的先自己想想。

试了一下，改成linear elements也可以啊，只是得把boundary也改成linear elements.

谢谢，呵呵，看看
