hi gd evening to everyone , i have one doubt , actually i did analysis with both hybrid initialization and standard initialization , in both method apart from results , i got converged solution in hybrid one but not yet in standard initialization , any particular reasons

Standard initialisation gives a single value for each variable over the entire domain.  Hybrid does some maths (look in the manuals) to give a non-uniform variable field which is usually closer to the converged model than standard. 

Depending on the model set up you can need a very good initial solution to reach convergence. It usually doesn't matter which you use, but if you have pressure in & out or multiphase the initial conditions can be critical to success.
