Hi, My system is 2D axisymmetric geometries,density is constant.In the outlet,I want to check whether mass balance, the following is some report from Fluent:

x-coordinate: 1.77E-20 y-coordinate: 2.90E-04 axial-velocity: -7.29E-03 radial-velocity: -1.23E-03 mass-imbalance: -2.23E-16 daxial-velocity-dx :5.06E+01 dradial-velocity-dx:9.88E+00 daxial-velocity-dy :-6.96E+01 dradial-velocity-dy:-3.24E+01

Anyon can tell me how to calcalate the mass balanceof this point?
