regarding under relaxation factors
 

sir,

is there any safe limit for specifying under relaxation factor for flow through pipe bend with 5.5 radius of curvature to radius of pipe ratio bend. The reynolds no.is 10000. the solution is not converging....

I would recommend you to go and check your mesh quality. I have done pipe-bend simulations like this before..and convergence was never a problem.
