I focus on spray simulation in contant volume chamber with kiva.
I choose the sector mesh for simulation.
The error message is as following.
error: sector=1.0 but cannot find a periodic boundary

however,i already set up the periodic boundary for the front and derriere face.

the following is my iprep.
