Hi guys

What’s up?

I was wandering if anybody knows

What is the “flow simulation” definition of steady state condition?

If I will do an 8h time depended analysis & run a non-depended time analysis the results will be the same?

What is the software steady state definition?

Appreciate the help!

Thanks

the definition of steady state is that the simulation will reach one continuous state (temperatures, velocities, pressures, etc. will reach a steady state).

For example, flow around a tube can continually oscillate downstream of the tube. This type of simulation may never reach a steady state (depending on boundary conditions).

For a time dependent simulation Flow Simulation saves each time step of information so you can look at the results as a function of time.

For steady state it saves the final converged answer as this is the "steady state" solution.
