[FAQ]

Data Sampling in steady-state:

1. In general, not advisable as may not represent a physical solution.
2. Some more or less plausible arguments can be made about pseudo-transient in situations when the solution settles into a quasi-oscillatory state indicating ongoing unsteadiness. In this case, one can argue that an average of the pseudo-transient solution could be representative of its steady state. In this case, this can be implemented via a straightforward user-defined function.
