谁知道振动技术在岩土工程中的应用现状？

我在管道分析中采用了三段橡胶支座,分析过程中出现:
***ERROR: THE NLGEOM FLAG MUST BE SET ON THE *STEP OPTION IF A HYPERELASTIC OR
           A HYPERFOAM MATERIAL IS USED.
***NOTE: DUE TO AN INPUT ERROR THE ANALYSIS PRE-PROCESSOR HAS BEEN UNABLE TO
          INTERPRET SOME DATA.  SUBSEQUENT ERRORS MAY BE CAUSED BY THIS OMISSION
请问我该如何解决呀?
谢谢啦!
