Domain imbalances

Hello
What's the meaning of the imbalances in a simulation.

If for example I got 97% imbalance (V-Mom) and 0% in all others?

Can I trust the results?

It's an unsteady simulation coupled with FSI.

Thanks,
Santiago

At the bottom of the output file it tells you - it is the global sum of that variable (eg U momentum), and the imbalance of the global sum is an indication of how tight the convergence has been. This sum is done across boundaries, source terms and anything else which affects the global conservation.
