Default strange things happen with slip boundary

Hi everyone:

I model 2d microflow with slip boundary for single-phrase.

Slip boundary given as follow:

u_wall=B*du_wall/dy

When i choose B=68nm,the slip velocity u_wall matches the analytic solution.However when i choose B=680nm,the slip velocity u_wall is twice as large as the analytic solution.

Until now,I haven't found the reason?Could you please help me ?

Best wishes!

lei wang
