when I run pimpleDyMFoam, this error occurred.... I don't know why it happens, what made this problem...

Have you checked your mesh?

I had a similar error. Turns out after performing some transformation the mesh failed 4 check test!

1. May be you should try more nCorrectors and lesses nOuterCorrectors

Code:
PIMPLE
{
    correctPhi          yes;
    nOuterCorrectors    1;
    nCorrectors         10;   // or 20 or 50
    nNonOrthogonalCorrectors 1;}
2. Try using PCG solver for p equation at the start until it runs fine and then switch to GAMG.
