Hi CFD Family,

Regarding my thesis project, I need to conduct a CFD simulation for my part. I am relatively new to CFD simulation. Although I attempted to proceed using YouTube tutorials, it did not work out in my case. I need to study the fluid behavior in the channels of my part. While I have done the meshing, its quality is very poor. The aspect ratio is 32, and the orthogonal quality is 0.06. I want to improve these two metrics. Could someone please assist me? I have very little time left to submit my thesis. I have uploaded pictures and the values I used for the meshing. Please kindly correct them and help me improve the mesh quality. (blue color is aspect ratio results and mixed colour is orthogonal quality )
Thank you.

To improve your mesh quality:

1. Refine Mesh Locally: Focus on areas with high gradients or complex geometry.
2. Use Advanced Meshing: Switch to hexahedral elements or add prism layers near walls.
3. Smooth Transitions: Ensure a gradual change between small and large cells.
4. Adjust Parameters: Tweak meshing settings to lower skewness and improve orthogonal quality.
