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.
