提示：Fluid-structure interfaces in fluid and solid models are not coincident
流固耦合求解报错提示信息如下：Fluid node (label) 1038 is not attached to solid fluid-structure
interface 1. The relative distance to solid boundary element
579 is 3.51E+00.
The fluid nodal coordinates are (-3.3E-02, 0.00E+00, -1.7E-02).
The points and their coordinates of the solid boundary element are:
point 1 = ( -3.35E-02, 0.000E+00, 0.000E+00)
point 7 = ( -3.31E-02, 4.992E-03, 0.000E+00)
point 295 = ( -3.31E-02, 4.992E-03, 5.000E-03)
Possible causes are:
* Fluid-structure interfaces in fluid and solid models are not
coincident;
* Solid boundary elements are too coarse compared with fluid boundary
elements on the same fluid-structure interface.
一、网上查询解决方法有：1、流体和固体的耦合面要对应（我的是对应的）
2、在MESHING-CREATEPOINT那里输入流固接触点的点号，在MESHING-ALE MESH CONSTRAINTS-FIX MESH 看你所选中的点是否被固定 这样 在重新画网格就可以了！（没找到MESHING-CREATEPOINT选项）
二、流体也流固耦合功能高级应用书上有这个典型错误，说是两个耦合面之间距离太大。
哪位朋友能给予解惑:handshake
