我在做瞬态分析，现在出现两个错误，不知道怎么回事，求大神支支招

1.

 Element 1 using isotropic material 1 has a value of Poisson's ratio of  

 11540 which must be greater than -1.0 and less than 0.5.

2.

 The step data was checked and there were errors found.                  

  Please check output or errors file ( F:\moxing\shangke\file04.err )    

 for messages.
