Convergence and Under Relaxation Factors- Dependency?

Dear all,
I am working on a project of under hood thermal management. My solutions were oscillating between a extreme minor difference, for some vales of URF. But when decreased the value of URF(Under Relaxation Factors) by small value, my solutions got changed, by a minor value. So my question is, Should the converged solution independent of URF value or not? IF not then how to know that we have a correct solution.?? Thanking You, Sidharth. |

The solution should not change, however that says nothing about how long you must run the solver with a lower URF to match the solution of the solver at a higher URF
