流固耦合计算中出现这样的问题，怎么办？
在流固耦合的计算过程中，计算不收敛，出现先变这样的提示：E:\ADINA\practise 16\prob-ff.dat + E:\ADINA\practise 16\prob-ss.dat

*** ERROR *** CODE ADF2702:
Fluid node (label) 56 is not attached to solid fluid-structure
interface 1. The relative distance to solid boundary element
2 is 1.00E+00.
The fluid nodal coordinates are (0.00E+00, 4.00E-01, 1.00E+00)
The points and their coordinates of the solid boundary element are:
point 2 = ( 0.000E+00, 3.000E-01, 1.000E+00)
point 3 = ( 0.000E+00, 3.000E-01, 9.000E-01)
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.
Recall that fluid-structure interfaces are specified in both fluid and
solid models. They must be coincident with each other. However, it is
normal to have a small distance between fluid nodes and solid
fluid-structure interfaces if meshes of interfaces in both models are
not matched.
The relative distance here is defined as the ratio of the distance between
the fluid node and the closest solid boundary element to the length of the
solid boundary element.

是怎么回事？请各位学长指教，
我是一个新手，谢谢指教 液体固体界面要一致 流固耦合界面未匹配好。 2# ccy7270801
