Introduction I

VIII International Phoenics Users Conference

• Special purpose tools for performing series of simulations of specific equipment

• Builds error free Q1 files based in equipment engineering inputs

• Controls access to PHOENICS modules

• Allows saving and reloading cases without loosing original input

Why develop a system like that ?

The system allows industrial equipment designers, whithout time to invest in learning CFD, take full advantages of the benefits of PHOENICS

Different data inputs

• boundary conditions• fluid properties• object positions• numerical settings• grid

• operational conditions• equipment geometry

User HMI VR Editor

Earth

VR Viewer

• User enters data for the selected tool or loads an existing case

• Interface checks the data for any non-acceptable value

• If no errors are found, IHM enables user to call VR Editor

• IHM enables the execution EARTH

• After execution is finished, user is able to run VR Viewer

Safety Features

VIII International Phoenics Users Conference

The System …

• checks for unnaceptable values(e.g.: interfering positions, unfeasible operating conditions)

• sizes the grid automatically, matching objects and suiting regions

• uses self adjusted relaxation parameters programmed in GROUND
