We start off by naming various faces of our geometry for later use in FLUENT and to make surface body referencing much easier when creating our mesh.

This really neat tool allows you to cut through the mesh in order to visualize its interior!

We start by applying specifying some global mesh settings which means that these settings will be applied to the whole mesh altogether.

After applying controls to the whole mesh, we now apply mesh settings to specific areas of our geometry.

We now show you how to judge the quality of your mesh. This is an extremely important step because a bad mesh can lead to bad results!

Summary of steps in the above video:
It is generally advised to keep the minimum orthogonality greater than 0.15 and maximum skewness lower than 0.95. Having bad cells or elements can lead to incorrect simulation results. However, these are general guide rules and depend on the physics solved or where the cells are located. The following tables can help you gauge the quality of your mesh.
Skewness:
Outstanding | Very Good | Good | Sufficient | Bad | Inappropriate |
---|---|---|---|---|---|
0-0.25 | 0.25-0.50 | 0.50-0.80 | 0.80-0.95 | 0.95-0.98 | 0.98-1.00 |
Orthogonal quality:
Inappropriate | Bad | Sufficient | Good | Very Good | Outstanding |
---|---|---|---|---|---|
0-0.001 | 0.001-0.15 | 0.15-0.20 | 0.20-0.70 | 0.70-0.95 | 0.95-1.00 |
