这是一个柔性机械手抓，在一侧同期可以进行弯曲从而抓取，想用硅橡胶这种材料进行，在做硅橡胶这种材料分析的时候，错误为
The initial bulk modulus of 2.01037e+08 exceeds 100 times the initial shear modulus of 3.77697e+05 (the initial poisson ratio 0.49906 exceeds 0.495) for the hyperelastic material named rubber. However, a hybrid type element is not used. This may cause convergence problems. It is recommended that you change the element type to a hybrid element; however you can also convert this error message to a warning message by setting the environment variable nonhybrid_incompress to warning or by adding *diagnostics, nonhybrid=warning to the input file (not recommended).

Analysis Input File Processor exited with an error.
我的参数都是在abaqus帮助文档找到的，不知道是不是材料的原因，真的很烦恼，谢谢各路大神帮助，如果有想试试的我也可以发模型，谢谢大神
