Hello,


Are you solving a diffusion equation in 3D? Is your diffusion coefficient a constant in all three directions? What is your mesh-like? Is it a structured grid you are solving this problem on? What are your boundary conditions? Also, what is your solver? Coupled or SIMPLE?


Thank you.


Best Regards,


Karthik
