Meshing: Elements and Types

This lecture covers the common types of mesh elements used in numerical flow simulation, such as tetrahedrons, hexahedrons, triangles, quadrilaterals, wedges, and pyramids. It explains the properties of each element type and their impact on the numerical approximation of gradients and fluxes. The lecture also discusses structured and unstructured mesh types, highlighting their differences in element connectivity and grid flexibility. Additionally, it emphasizes the importance of mesh quality, including element size, distribution, and shape, in achieving accurate and efficient numerical simulations.
