DESCRIPTION
Short Presentation on the use of Augmented Reality to visualize Computational Results. In this work results obtained using Star CCM+, Vuforia and Unity 3D are presented. Test Case BMW Z3. The present Scenario and a possible future Scenario are described. The strategy successfully deals with other CFD, FEM and Meshless codes simulating a variety of different simulations (combustion, buildings, mixing, aerodynamics...)

Overview
What is Augmented Reality (AR):
“Augmented reality (AR) is a live, copy, view of a physical, real-world
environment whose elements are augmented (or supplemented) by computer-
generated sensory input such as sound, video, graphics or GPS data.”
Why Augmented Reality (AR):

Augmented Reality:
1. Wikitude
2. Metaio
3. D'fusion Studio
4. Vuforia
“…there is little doubt that the future of AR is not in smartphones or
tablets, but in more natural, eyewear-based interfaces.
The real question is when that future will actually begin…”

Natural Feature Tracking (NFT) Setup - Vuforia
Augmented Reality requires a reference (virtual point) or a real target to
project and overlap the virtual content.
For the cases here presented, the NFT Target Method is used.
Image Targets are pre-processed using the provided online Vuforia Target
Manager
1) Background:
Augmented Reality in CAE used to visualize CAD 3D models
CFD/FEM:
From 2D Pictures to 3D Virtual Reality (Head Mounted
Display, Stereoscopic Glasses, Immersive Reality…)
How Augmented Reality will be used in Computational
Engineering:
Available Technology: Mobile, Tablet quadcore , 2Gb RAM
Binocular See-Through Vision Glasses will be Released in
2014 (Pre-Sales)
Data Conversion required
Augmented Reality (AR) in Computer Aided Engineering (CAE)
Augmented Reality for Numerical Computing (CFD/FEM) :
AR Extends the Range and the Visualization
Possibilities/Capabilities of Commercial and Academic Scientific
Data Rendering (Image Post-Processing)
AR Increases Visualization Performance of Data Sharing
and Client Data Delivery/Presentation
Focus on:
Multiple Element Interaction /Coupling
Turbulence, Vortex Shedding…
Flame Stability
