abaqus的网格节点问题？

本人在建船体和下沉龙骨的模型，如果船体和龙骨的节点共用，如下图，abaqus就无法计算，出现：

The executable standard.exe aborted with system error code 1073741819. Please check the .dat, .msg, and .sta files for error messages if the files exist.  If there are no error messages and you cannot resolve the problem, please run the command "abaqus job=support information=support" to report and save your system information.  Use the same command to run Abaqus that you used when the problem occurred.  Please contact your local Abaqus support office and send them the input file, the file support.log which you just created, the executable name, and the error code.

但是如果两者节点不共用，如下图，算是能算，但结果肯定不对啊

所以求各位大神帮帮忙啊，毕业论文写不了了o(╥﹏╥)o
