Problem with checking the divergence of flux

Hello,

I am solving a 2D problem with transport of diluted species equation. The equation is set to be

divergence Flux = 0

and after solving, when I check the divergence of flux at each mesh point, d(x_flux,x)+d(y_flux,y), the value is not equal to 0 at all the meshing points. I wonder where did I do wrong. The domain is rectangle with rectangular meshing.

Can someone enlighten me on this part?

regards,
Hansong
