Hi guys, I've searched this forum for a thread about starting a steady-state simulation using local timescale but unfortunately, I didn't find any (or maybe my search key is just off). Also, I found the FAQ topic regarding using the local timescale factor for simulations needing tighter convergence/oscillating residuals, but this is for when the simulation is in progress.
So my question really is: is it ok to start a steady-state simulation with the set initial conditions using a local timescale factor? I already tried this and got a pretty good monotonic convergence (though the rate of convergence slows down later on and the wall scale does not disappear). What are the implications in the numerics when I use the local timescale factor at the beginning, since what I usually read about local timescale factor is "only use them when the flow is complex, and with uniform elements and moderate aspect ratio"? Thank you in advance to those who will answer my question! |
