problem description:a passage of impeller, a passage of diffuser and a volute. during the solving,the mass flow of inlet and outlet are steady,but they aren't equal. I don't know why? the interface of diffuser and volute is "stage", is it right?

Are you checking both the inlet and outlet of rotating frame ?

Both the inlet and the outlet are static

I mean where are they located ?, can you mark them in your figure ?
It might be possible, u r seeing a single passage value at inlet and a full passage value at exit

"stage" is wrong. you need "frozen rotor"

At inlet is a single passage value, and at the outlet is a full passage value.
