We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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.
