Residuals not converging

Hello,
I have a problem with my residuals not converging. For my Master Thesis I need to simulate the Flow of a transformer housing. Im doing a steady simulation using realizable k-epsilon turbulence model with capable wall functions. As you can see, after some time the residuals, especially the continuity residual are not converging anymore. I also put some monitor points in the domain. The velocitys at the monitor points are oscillating around a value. It seems like the problem is transient and not steady, am i right? I already tried refining the mesh, but no difference. Does somebody know, what might be wrong with my simulation or do i have to do a transient simulation? The steady simulation already took 20 hours so a transient simulation would take a lot more time I guess. I´m quite new to cfd so please dont hate if it is a stupid question. |
