Hi everyone,
This is aerror tips,how to solve it,I have read something about this error's mean,and i have changed boundary conditions,but it still appeaer error,i am prepare to compute changable speed in pump,if rotating speed constant,this error would not appear,please help me!

tannk you for replying, i have read this link before you recommend to me,but i have tried some ways ,it's still useless,i simulated a pump working conditions wnich is starting period,rotating speed and mass flow are changing,the formula of rotating speed is y(t) = 12.039t^3 - 81.768t^2 + 188.72t,
CFX calculates six or seven steps will appear this error,How to solve it?thank you!

thank you for helping me,i have solved this problem,i changed time step from 0.001 to 0.0001,it's not appear error tip at present,i think mabe i used mesh motion,in a word,thank you enthusiasm to help!
