流固耦合 流体网格拉伸的遇到的问题

iletelle

做了一个固体在流体中旋转的例子，用到FSI和网格控制leader-follower.

固体在流场的一侧旋转带动流体运动，计算流场内部压力的变化。请大家帮忙看一下为什么会出现这样的计算结果？流场网格为何不能均匀的被按照弧形拉伸？ 不收敛提示错误为。 我后来又做了一个是平动而非旋转的例子，结果是可以顺利计算下去的。
请大家帮我解决下这个问题。
*** ERROR *** CODE ADF2704:

    Fluid node (label) 274 is not attached to boundary geometry 6.
    The relative distance to boundary cell 1 is 1.25E+01.
    The fluid nodal coordinates are (0.00E+00, -3.6E-01, 6.18E-01)
    The points and their coordinates of the boundary cell are:
        point       1 = ( 0.000E+00, 1.500E-01, 7.000E-01)
        point       2 = ( 0.000E+00, 1.899E-01, 6.902E-01)

    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.

你用动网格了没？
