I'm modelling a gas turbine combustor with an unstructured grid. I've got a problem for the continuity residuals. I don't think it's a problem related with the grid.

I tried several unstructured grid (sensitivity analysis). Could I change under relaxation factor?

Decreasing of under relaxation factor usually help. Especially the Momentum under relaxation factor.

Decrease under relaxation factor. first momentum, if it not sufficient then try with pressure also.
