Dear Merva & Rob,

Thankyou for your guidance.

Yeah the whole geometry is being meshed. I have put local sizing to internal domain with inflation layers and after playing with some sizing, the total cell count reduced to 2,159,730 (2.15M). I have used the poly hexcore mesh and minimum orthogonal quality is around 0.19. 

But the calculation time is still very slow. I am using eulerian multiphase model. 

How can i improve the computational speed of my simulation. 

I have done another simulation with different geometry of same nature & cell count was 1.6M at that time and polyhedra cells was used. the computational speed of that simulation is much better than today's simulation.
