求助！流固耦合问题

2519200

我用3D建了一个流场和一个部分浸入水中，在水中摆动的摆板，in文件附在后面，出现了三个问题：
   第一个问题是为了流体划分网格所以把流场实体分割了，结果不能把有接触的面都定义自由表面条件了，请问这个想把整个自由表面都定义上有什么方法？
   第二个问题是计算结果不能出现预想的摆板随水流摆动，水流遇到墙面反射的波面形状；
   第三个问题是计算过程中会出现
*** WARNING *** CODE ADF2703:

    Fluid node (label) 88 is not attached to boundary geometry 1.
    The relative distance to boundary cell 14 is 7.542E-01.
    The fluid nodal coordinates are (5.00E+00, 5.00E+00, 7.67E+00)
    The points and their coordinates of the boundary cell are:
        point      14 = ( 5.000E+00, 5.000E+00, 6.000E+00)
        point      15 = ( 4.100E+00, 5.000E+00, 7.000E+00)
        point      16 = ( 5.000E+00, 5.000E+00, 7.000E+00)

    It is normal to have a small distance between fluid nodes and boundary
    geometry. The relative distance here is defined as the ratio of the
    distance between the fluid node and the closest boundary cell to the
    length of the cell.

    Note: The boundary geometry is internally generated by the program.
之后计算改变算法直到10阶，然后自动跳出运算。
