aspen模拟出错

zzw67339

自定义的组分，然后运行完显示反应器出错，反应器用的RStoic，具体错误：
** ERROR
   FLASH RESULTS ARE WITHIN TOLERANCE, BUT MAY BE UNSATISFACTORY BECAUSE
   EXTRAPOLATED EOS VAPOR VOLUME ROOT WAS USED FOR PROPERTY CALCULATIONS.
***SEVERE ERROR
   FLASH CALCULATION NOT CONVERGED, SIMULATION CONTINUES
不知道从哪下手，麻烦各位大神帮帮忙啦
