Avizo Wind Software Used to Study the Great Sphinx Erosion
The Great Sphinx is a monumental statue that is considered the first
truly colossal sculpture in Egypt and a national symbol of both ancient
and modern Egypt. The statue would have disappeared long ago had it not
been buried under sand for so long. The statue is eroding due to the
effects of wind, humidity and the smog from Cairo. Wind is one of the
most critical denudation factors that are causing the erosion of the
statue, especially when it carries dust. In order to investigate the
formation of the low speed wind over the Sphinx model, a simulation is
made that involve solving the 3D incompressible Navier-Stokes equations
on a several millions of points’ computational mesh. This is a
collaborative work between IBM and Bibliotheca Alexandrina based on
research work conducted in IBM Center for Advanced Studies in Cairo.
The VISTA team Of Bibliotheca Alexandrina has implemented the
visualization of the simulation results on the CAVE system using Avizo
Wind to provide new insights and better understanding. Thanks to the
calculation and visualization of complex algorithms, (Stream Ribbons,
Line Integral Convolution (LIC) Algorithm, Illuminated Stream Lines (ISL)
Algorithm and Vorticity), the researchers can see the invisible,
understand the degradation of the Great Sphinx and present their result.
"The VISTA team has chosen Avizo Wind because of its ability to
display and manipulate meaningful graphics representations of natural
phenomena. Using Avizo Wind, VISTA is able to use advanced visualization
techniques to understand complex simulation data."
Avizo Wind 6 is available for Windows (32-/64-bit), Linux
(32-/64-bit) and MacOS.
