The dataset consists of an unstructured grid with solution.

In far more complex geometries it is logical to use large number of blocks and therefore it leads to unstructured grids.

Various automatic techniques especially those associated with Finite Element Method also utilize unstructured grids.

Mesh refinement and adaption is easy in unstructured grids.

Mesh (mathematics) or a regular grid or unstructured grid .

Ruppert's algorithm is often used to convert an irregularly shaped polygon into an unstructured grid of triangles.

One of the most commonly used algorithms to generate unstructured quadrilateral grid is "Paving".

However, there is no such commonly used algorithm for generating unstructured hexahedral grid on a general 3D solid model.

It is most common in unstructured grids.

An unstructured grid is identified by irregular connectivity.
