分别是DSYWU和进料
一直出现
  *** SEVERE ERROR
   FLASH CALCULATIONS FAILED TO CONVERGE IN  15  ITERATIONS. BUBBLE POINT
   CALCULATION HAS DRIVEN THE TEMPERATURE DOWN TO THE LOWER LIMIT OF
   95.3202 DEGREE K.  BUBBLE POINT TEMPERATURE MAY NOT EXIST AT THE
   SPECIFIED PRESSURE.  FLASH RESULTS ARE WITHIN TOLERANCE, BUT MAY BE
   UNSATISFACTORY BECAUSE EXTRAPOLATED EOS VAPOR VOLUME ROOT WAS USED FOR
   PROPERTY CALCULATIONS. BUBBLE POINT FLASH OF BOTTOMS FAILED.  BLOCK
   BYPASSED.

求教怎么解决
