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 .

someone told solver calculates the rho field explicitly so it doen't write it.
but I am still in doubt.
can somebody help?
