How solver works?i.e. after solver starts how it calculates values of pressure and velocity?does it initially take all values zero?This is as i have observed when solver is running?

This is not a simple question...The solver starts with the values u have utilized to initialize the case. Elsewhere I think it takes 0 or default values. Pressure and velocity are coipled in the momentum equation, so the solver needs a 2nd equation that is a mathematical algorithm like the SIMPLE or PISO.

The solver takes the initial P and V values as zero unless you specify you IC/BCs.
