Introduction I

• 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

Introduction II
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
With the HMI
Without the HMI

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

• operational conditions
• equipment geometry

Accessing PHOENICS ...
User
HMI
VR Editor

• 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

Safety Features

• 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

Benefits of the System

• Sensibility analysis
• Brings PHOENICS to day-to-day activities of
  equipment designers
• Time saving starting point for similar
  specific simulations
• Helps spreading CFD concept
• Modular architeture New tools
