zero rho,rhoUx,rhoUy

in my results at each time step rho equations doesn't been solved in rhoCentralFoam.why?
thank you for helping.I need a lot to solve this problem
what should I do?please guide me through solve the problem.thanks.

zero rho,rhoU

Hi ehsan,

I have the same problem with rhoCentralFoam .
