Try altering the under relaxation factors for whichever residuals are 'blowing up'. Also, if its an unsteady simulation (as it probably should be), try decreasing the time step a little.

i tried altering the underrelaxation factors and then i get convergence detected in AMG solver kinda error.And my problem is with steady state...so no time steps at all.though i want to solve unsteady ,i get errors in the initial level(at say 20-30 iterations)plz give me more parameters to check with.thanks.
