求助ansys做转子动力学遇到的问题

求助ansys做转子动力学遇到的问题用ansys做转子动力学时,遇到如下提示:At least one of the frequencies is unstable. Instability check is mode on real part of eigenvalue. If damping is very small,re-runing the model using another eigensolver is strongly .recommend to double-check the instability prediction
请问是何原因,如何解决呢?
