Most models use meshes which are either structured (Cartesian or curvilinear grids) or unstructured (triangular, tetrahedral, etc.). Gerris is quite different on this respect: it implements a deal between structured and unstructured meshes by using a tree data structure, [a] allowing to refine locally (and dynamically) the (finite-volume) description of the pressure and velocity fields.

Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Below is a structured list of topics in fluid dynamics.
A direct numerical simulation (DNS) [1] [2] is a simulation in computational fluid dynamics (CFD) in which the Navier–Stokes equations are numerically solved without any turbulence model. This means that the whole range of spatial and temporal scales of the turbulence must be resolved.
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).
He usually finishes in the 10-20 range among quarterbacks when all the points are added up. But he did have his sharpest game of the season a week ago, throwing for three touchdowns and finally ...
The Richardson number (Ri) is named after Lewis Fry Richardson (1881–1953). [1] It is the dimensionless number that expresses the ratio of the buoyancy term to the flow shear term: [2]
