Segregated Steps Order

Hi everyone,

I have a mass transfer equation with two reaction source terms which is coupled with fluid flow and energy equation. I've tried fully coupled solver, but it didn't work. I'm going to run the simulation with segregated solver. does anyone have similar experience and know which order of segregated steps is best for these kind of equations?

also, there are two columns in LOG, SolEst and ResEst, when I choose "solution or residual" for termination criterion. I know that these are Solution estimate error and Residual estimate error which are defined differently. I just want to know that what is the reasonable order of magnitude for SolEst and ResEst? even in converged problem they are too different (10e-9 for SolEst and 10e3 for ResEst when the relative tolerance is set to 10e-8)

any kind response would be appreciated, Sadegh
