Hi all,

I checked the example (scalar_time_int.mph) from COMSOL Knowledge Base (comsol.com/support/knowledgebase/913/) which discusses about Computing Time and Space Integrals. I assume that the moles cased by the flux in and out (Inmol-Outmol) would be consistent of moles by integrated over the whole domain (in this model it is Mol). It means that Inmol-Outmol-Mol=0. But the results doses not agree with this. Could anybody give some hints/comments on why this problem happen and how to figure out the consistent due to diffusion in this example model?

Thank you very much.
