ADINA二维流场内流固耦合问题,总出现ADF2072

zhugy

模型如下图所示
固体部分为两个薄片,设置了两组流固耦合界面.


流体

固体


计算时报错ADF2072, 看错误提示应该是合流固耦合界面间隙过大有关.
但是如果将下部或上部薄片去掉后,使用相同条件即可计算...模型的尺寸上应该没有问题..,


求各位高手给予指点!!

** ERROR ** CODE ADF2702:

    Fluid node (label) 2806 is not attached to solid fluid-structure
    interface 1. The relative distance to solid boundary element
    51 is 1.00E+01.
    The fluid nodal coordinates are (0.00E+00, 5.00E+01, 5.00E+00)
    The points and their coordinates of the solid boundary element are:
        point      21 = ( 0.000E+00, 5.000E+01, 6.000E+00)
        point      66 = ( 0.000E+00, 5.000E+01, 6.100E+00)

    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 eleme

流固耦合面编号不对应

这样的编号应该怎么编呢？
