convergence problem
1 Attachment(s)
Hi all,
I have problems in getting convergence for an unsteady simulation. the continuity residuals do not fall down below 4*10^-3. changing URF's does not make a difference. what surface monitors can I use to check convergence? since there is no steady state solution for my problem, every quantity like pressure and velocity will change in domain. how can I deduce convergence from surface monitors? Below is the picture of the residuals. any ideas? |
It is going to depend on your simulation. Typically, I monitor mass/volume flow rates across boundaries. Unsteady simulations are usually a little more difficult to judge convergence based on residuals.

I don't have any mass flow rate. my problem is a bubble collapse simulation. I cannot check pressure or velocity in domain since it is changing constantly. I don't now if my simulation is converged or not?
