2011 EDEM Visualization Contest Winners’ Gallery
Thank you to all the EDEM® users who submitted simulation images to this years’ contest.
DEM Solutions received videos and stills from EDEM® and EDEM Academic™ users around the globe.
The entries represented a wide range of EDEM applications in engineering design,
industrial R&D and academic research -- addressing a broad spectrum of
bulk materials handling and processing challenges across a wide range of industries.
We are proud to showcase the winning images in the gallery below…
Welcome to the 2011 Winners’ Gallery!
Congratulations to the winners in both the Videos, and Stills categories and many thanks to all who entered the contest!

1st Place
Andrew Hobbs
Astec Industries
Asphalt production equipment
This EDEM simulation shows mixing of asphalt aggregate in the outer chamber of the Astec Double Barrel™ drum mixer.
What the judges thought…
“
The combination of high number of particles and complex rotating machinery
in this mixing application show the standard functions of EDEM applied
at their best. The analysis, including realistic template-based
representation of the material, highlights the complex velocity
flow profiles.

2nd Place
Wesley Kieser
DRA Mineral Projects
Mining services
This EDEM simulation shows a chute capable of transferring bulk material
(size distribution -32mm to +15mm) to a choice of three different conveyors,
at a rate of 585 tonnes of ore per hour.
What the judges thought…
“
Use of the orthographic viewports clearly highlights the flow of material in this conveyor transfer chute system.
The design allows stopping the center conveyor and blocking a side leg, so that
the material can buildup and then flow to the selected side -- the coloring and
stream representation clearly show the dead zones within the model.

3rd Place
Knut Krenzer
IFF Weimar
Precast concrete technology
This EDEM simulation shows the mixing process of dry and wet particles.
Depending on the moisture content, cohesive forces act on the particles.
What the judges thought…
“The technical complexity and analysis shown in this model is commended. IFF Weimar has used the EDEM Advanced Programming Interface to introduce their custom model for mixing with cohesion. The analysis techniques in showing their custom model, which applies cohesive forces between the materials, are impressive. Comparison with experimental data shows the fit-for-purpose predictive ability of this model.”

Honorable Mention
Gregor Toschkoff
Research Center Pharmaceutical Engineering
Pharmaceutical process- and product-development
EDEM simulation of tablet coating operation in the pharmaceutical industry.
Used to investigate and optimize the coating process by simulating movement
and mixing of tablets.
What the judges thought…
“Good use of visual analysis techniques that include CAD template representation, selection groups and streamlines to enable the evaluation of mixing.”

Honorable Mention
Nima Gharib
McGill University
Research university
The EDEM Field Data Coupling module has been used to model
particles such as lunar dust and simulate transportation by electrostatic forces.
What the judges thought…
“
This planar electric curtain simulation video highlights the advanced capabilities of EDEM.
McGill has made use of the Field Data Coupling module to import multiple electrostatic fields
and reproduce the forces applied by this field on the particles.

1st Place
Jean Brummer
VR Steel
Steel products for mining industry
EDEM simulation of a conventional VR Steel dragline bucket design (with a full set of rigging),
achieved by coupling 105 individual components between MSC Adams and EDEM. Gives
valuable insight into hoist & drag forces, optimal carry angle, and optimal
design for soil flow.
What the judges thought…
“
Impressive use of geometry import capability for this large scale application. Realistic material representation, using appropriate coloring and CAD templates, brings the image to life.

Nima Gharib
McGill University
Research university
The EDEM Field Data Coupling module has been used to model particles
such as lunar dust and simulate transportation by electrostatic forces.
What the judges thought…
“
Great example of Field Data Coupling and how it can be used to address complex problems such as the electrostatic cleaning of dust from a screen.

3rd Place
Andrew Hobbs
Astec Industries
Asphalt production equipment
EDEM simulation of a Roadtec Shuttle Buggy® showing
internal remixing of asphalt material to eliminate
temperature segregation before transferring to paver.
What the judges thought…
“
Very impressive use of CAD and geometry shading to contextualize the flow of material as it is processed through the machinery.
Heat transfer between the materials is shown over a long simulation time period.

Honorable Mention
Nima Gharib
McGill University
Research university
EDEM virtual prototype of the iRing, a new innovative idea for the lunar
rover--a wheel made of a chainmail-type fabric filled with granular material.
What the judges thought…
“
One of the most complex shapes created by multi-sphere and groups of multi-sphere particles ever seen. Shows the wide range of capabilities and shapes that can be created using EDEM’s multi-sphere capacity.

Honorable Mention
Nick Brown
University of Edinburgh
Research university
EDEM simulation image of a concrete cube (150,000 bonds between 12,000 particles),
superimposed onto a photo of a real concrete cube. Both cubes are destined to be
crushed in a compression test and the results compared.
What the judges thought…
“
Great way of reminding ourselves that we are trying to address the challenges of real materials in the real world, such as modeling concrete structures.

Please join us in congratulating the Contest Winners, and the Honorable
Mentions, as we celebrate the many ways they use EDEM simulation
technology to visualize bulk particle behavior!
