heat transfer problem
 

i used hot room case from buoyantSimpleFoam but there is a problem in floux outflow ,i am new to openfoam

Continuity error cannot be removed by adjusting the outflow.
Please check the velocity boundary conditions and/or run potentialFoam to initialise the outflow.
Total flux : 5.88023e+06
Specified mass inflow : 21.4527
Specified mass outflow : 0
Adjustable mass outflow : 0
