Residual level setting of Fluent

I am working on a simulation about hydrodynamics of gas-particle system in a riser, and the solid volume fraction profile is an emphasis. My question is: is the default residual setting of 1*10-3 adequate to my project, if not, what are generally they?
Another question about the setting of residua is: I try to solve a transient problem using the setting of residual at 1*10-4. Since the problem is transient, the beginning of solution is very hardly converged with this setting. Is it possible that I can change the setting of residual to 1*10-3, and let the solution converged, once the main variable such as velocity or solid concentration is stable (no change in further iterations), and then change the residual setting back to 1*10-4. After monitoring the change of main variable, if the variable is again stable and converged with this new setting, can the solution obtained in this way be counted as a converged solution with the residual setting of 1*10-4? Thanks for any reply, |
