Hey! I started working on a different geometry with similar boundary conditions. attempting to do an incompressible flow first.
I’d like some input on simulation control, how much should my end time be ?
ideally a steeady state in my case would be good enough for 10 seconds of real time (the time for which my condition would persist in real life )
also, how much should my relative tolerance aim should be , i did a sim successfully with a relative convergence of 0.01 and 0.3 as relaxation factors. my absoulte residue target for p, u, k etc were at or less than 1e-5 but my post processor values dont make sense…
should i play around a lot with factors such as gauss limited corrected etc ?
No. i have simulated once but the results were wrong. I recently found an air intake simulation done by milad mafi and amd attempting to replicate it .
Jeet already gave me some more details: “sim in first link. basic run, run 6, run 7. the values converge but expecting a plenum pressure ranging from 98kpa to 70kpa …”
