Hi FMDenaro

Sorry for this late reply, I was busy with my coursework.

I tried out your suggestion and it worked out. The QUICK solver for 3d lid driven with periodic spanwise condition is...

Hi FMDenaro,

Thanks for your reply.

I tried refining the grid and ran simulations till 120x120x120 with no convergence. I came across some literature where the author uses third order Upwinding...
