how can we check, that the domain for which we make calculation, is following all conservation laws???

thank you.

Hi,

Looks at the mass, momentum, energy imbalances. There will also be imbalances for additional variables, volume/mass fraction etc.

Thanks Glenn:

would you please tell me; can we get a report of how much mass is flowing at a perticular time, as we get in the fluent. if it option is there than tell me how?

Hi,

Yes, that is easy. Set up a monitor point under the output settings with an expression something like massFlow()@BoundaryName. Have a look in the CFX Reference manual in the section titled CEL Expression language for more detail on CEL.

Actually, flows are already written to the mon file (which the Solver Manager reads from the run directory to make plots). Just create a new plot in the Solver Manager and pick the appropriate boundary region under the FLOWS section.
