As you can see in this 2D-hexahedral image(Click link), is this mesh a structured mesh or an unstructured mesh?

Not all mesh sizes are the same.

Thank you for reading my question.

It really depends on how the cells are interconnected. If its 2d, its a quad not a hex. Hexahedron only comes in 3D.

In CFD (Computational Fluid Dynamics) analysis, a structured mesh is a specific type of mesh generation used to discretize the computational domain. Here's a breakdown of the key characteristics:

Structure:

Elements: Structured meshes consist of elements that have a regular, repeating pattern. These elements are typically hexahedrons (3D) or quadrilaterals (2D).
Implicit Connectivity: The connectivity between elements is implicit in a structured mesh. This means that the neighboring elements for any given element can be easily identified based on its position in the grid. Imagine a checkerboard pattern – each square "knows" its neighbors based on its location on the board.
