CFD Online Discussion Forums - Continuity error

Hi, i´m simulating flow through a box with 2 vents containing 6 spheres, when i run the simulation it gives me error

--> FOAM FATAL ERROR: 

Continuity error cannot be removed by adjusting the outflow.

Please check the velocity boundary conditions and/or run potentialFoam to initialise the outflow.
