Abaqus的aqua模块不能加载到shell单元吗？

我试了查了 help文件
3.10.1 Aqua load cases

Product: ABAQUS/Standard
I. Full submergence of structural members

Elements tested
B21    B21H    B22    B22H    B23    B23H    B31    B31H    B32    B32H    B33    B33H   
ELBOW31    ELBOW31B    ELBOW31C    ELBOW32   
PIPE21    PIPE21H    PIPE22    PIPE22H    PIPE31    PIPE31H    PIPE32    PIPE32H   
RB2D2    RB3D2    R3D3    R3D4   
T2D2    T2D2H    T2D3    T2D3H    T3D2    T3D2H    T3D3    T3D3H   

Problem description
The structural member (beam, pipe, elbow, or truss) is kept straight and constrained, and it is moved to different positions and orientations in different steps; where appropriate, it is given a uniform velocity and acceleration. The structural member is subjected to various drag and buoyancy loads in the different steps. The problems are described in detail in the input files. The *DLOAD and *CLOAD options are tested in these problems. The effective axial force (output variable ESF1) for beam, pipe, and truss elements is also tested.
我自己加载的过程也出了错，难道船体的波浪载荷也用梁单元算？困惑中，望高手指点

我需要模拟平台，同样用aqua，不知道楼主找到合适的单元了吗

aqua应该是要加载在管土相互作用单元上

怎么管土相互作用单元上呢？？？？

AQUA中波浪载荷的加载是基于Morison公式，而Morison公式适用于小构件（特征尺度与波长之比小于0.2），因此使用的单元都是圆柱体，对于体单元或壳单元可能就需要自己计算载荷了~~~
