Non-positive volumes exist
 
Help~~

I ran a fan project, set steady solver and B.C interface for rotor. After more than 7000 iteration, residual of continuity reduced to 10^-4, and flowrate was reasonable too, then I changed solver to unsteady, and motion type from "moving reference frame" to "moving mesh", and continued to iterate, but the error message said " non-positive volume exist". How should I solve this problem ?
