Tips & Tricks

Why it is useful to describe problems in terms of non-dimensional parameters and which ones are the main important in solidification?

A dimensionless quantity is a quantity without any physical units. Such a number is typically defi ned as a product or ratio of quantities which do have units, in such a way that all units cancel. Dimensionless quantities are widely used in the fields of physics and engineering but also in every day life.

Influences of Solidification Length and Pressure Intensification on Gas Shrinkage Microporosity in Casting Components

Porosity in castings is a major defect since it affects the mechanical properties. In particular porosities are sites for the initiation of fatigue cracks. Therefore, the reduction of porosity fraction and size, the control of porosity distribution and morphology are crucial for the optimization of mechanical resistance of as cast components.

Inverting Models in CFD-CADalyzer

Computational Fluid Dynamics (CFD) requires the discretization of a geometry bounded by it's wetted surfaces. In CAD, the solid parts are created without the corresponding fluid volumes, i.e. negative space.

Blanking, Grouping and Selecting Entities in CFD-CADalyzer

When working with models in CFD-CADalyzer, especially the more complicated ones, Blanking, Grouping and Selection tools can considerably simplify model setup and visualization.

Automatic Report Generator in CFD-CADalyzer

The Report Generator in CFD-CADalyzer allows a user to generate and print a detailed report of the CFD simulation that has been set up and run. The user can also customize the report to make it fit his/her needs and demands.
