Diverging Eulerian Multiphase
I am simulating particles in the air.
The geometry is a room and a candle inside.
When I try steady state, it shows from the beginning floating point.
When I use Unsteady with low relaxation factors, it works to some extent, but whenever I change it to steady state, again it starts to diverge.
Any advice is highly appreciated.
Looks like an Eulerian multiphase simulation, right?
In that case, run it laminar, it's very unstable when running it turbulent.
Another try is to reduce under-relaxation factors to very very very low numbers.
Or even better: Try both at the same time!
I understand that's not satisfying, but unfortunately the Eulerian approach is very unstable under turbulent conditions. There are too much equations affecting each other.
Thanks abdul099, it is so nice of you :)
Did you get the solution with steady state?
I have the same problem.
can you help me!
thanks in advance
