Preprocessing, Solving, Postprocessing

Preprocessing

The first step for any analysis is the setting up of the problem. This includes the creation or importation from a CAD file of the problem's geometry (i.e. the control volume) the assignment of boundary and initial conditions, and the generation of the mesh.

Calculation

In this step the CFD solver does the flow calculations and produces the results. It provides a large range of physical models which have been all validated against industrial scale application:

• ventilation and conditioning system
• contaminant dispersion phenomena analysis
• industrial and biological application
• flow separation analysis
• flow, turbulence and cavitation analysis
• heat flow into fluid and solid material
• pipe and valve load loss calculation
• form optimization

The target of validation tests is obtained by general formulation for incompressible fluid flow analysis using the finite element method. The necessary stabilization for dealing with convective effects and the incompressibility condition are introduced via the Finite Calculus method using a matrix form of the stabilization parameters. This allows modelling a wide range of fluid flow problems for low and high Reynolds numbers flows.

Postprocessing

This is the final step in CFD analysis, and it involves the organization and interpretation of the predicted flow data and the production of CFD images and animations.
High-resolution images and animations are powerful tools with which it's possible to explain the problem results in a quick and impactful manner.
