Hi, everyone!
I'm modeling separation of liquid film from the surface throught the slit. Thikness of the film is very low (about 40 micrometers). Thus I have to use hight quality mapped mesh with cell size 1x1 micrometer. I use pressure inlet and pressure outlet boundary conditions, Eulerian multiphase model, laminar viscous model and define liquid film thikness by profile (principal scheme is shown on the picture).

The quality of grid is very hight, but in few iterations I got divergence detected(((
What can you advice?

Regards,
Vitaliy

what is exactly the message given? I mean where is exactly the divergence momentum, temperature pressure?

temperature limited to 1.000000e+00 in 51 cells on zone 11 in domain 2
temperature limited to 5.000000e+03 in 22 cells on zone 11 in domain 2
