Mesh Quallity

Mesh quality
• For
the same cell count, hexahedral meshes will give more
Accurate solutions,
especially if the grid lines are aligned with the
Flow.
• The
mesh density should be high enough to capture all relevant
Flow features.
• The
mesh.
Solver Study: Turbulent Flow Models
Turbulence
Turbulence or turbulent flow is a flow characterised by random and chaotic fluid flow with unexpected property changes.
Turbulence Models
A turbulence modelling is a computational procedure to close the system of mean flow equations..
Solver Study: Inviscid and Laminar Models
Inviscid Flow
An inviscid flow is the flow of an ideal fluid that is asumed to have no viscosity. In fluid dynamics there are problems that are easily solved by assuming that the flow is inviscid. It is a flow in which the viscous effects can be.
