Unraveling the Mysteries of Turbulence Transport in a Wind Farm

by Earl Duque | July 6, 2015 12:13 pm

A joint paper with Prof. Sven Schmitz was just issued in the ”Wind Turbine 2015″ special issue of the online journal Energies[1].


This paper entitled “Unraveling the Mysteries of Turbulence Transport in a Wind Farm[2]” is co-authored with Pankaj K. Jha 1, Earl P. N. Duque 2, Jessica L. Bashioum 1 and Sven Schmitz 1,*


For this project, we used FieldView XDB workflows[3] to enable the investigation of “mysteries involved in the recovery process of the wake momentum deficit, downstream of utility-scale wind turbines in the atmosphere.”  The “High-resolution surface data extracts provide new insight into the complex recovery process of the wake momentum deficit governed by turbulence transport phenomena. “

Intelligent Light is using SBIR grants to tap the
power of VisIt, a visualization program supported in
part by the Advanced Scientific Computing Research (ASCR) program in the Department of Energy (DOE) Office of Science.


Intelligent Light was selected as a trusted vendor who could provide the expertise and discipline to tailor tools to industrial workflows while commercializing and hardening the government developed code.  Intelligent Light is providing industrial grade software development, engineering service and customer support to end users.


The project enables Intelligent Light to hold down development cost and end-user investments by utilizing open source code developed by DOE.  Moreover, the project is helping Intelligent Light customers move to in-situ post-processing years earlier than if IL had developed all of the required technology from scratch.


Eric Brugger and other Lawrence Livermore National Laboratory scientists designed VisIt to visualize the mounds of simulation data DOE supercomputers generate. It’s built to scale well and it’s well suited for in situ processing.


“VisIt … is an open-source code, free to download and modify, as thousands of researchers have. With no licensing fees, merging VisIt into FieldView will hold
down costs for small- and medium-sized companies using it on HPC systems.”

Intelligent Light responded to a call by ASCR to harden and commercialize DOE-supported software for high performance computing applications, making the tools robust and accessible.  Working under a Phase II grant of nearly $1 million, Intelligent light is integrating VisIt into our FieldView HPC suite. The funding is from a U.S. Small Business
Innovation Research (SBIR) program, which provides capital for early research and development with commercial potential.


VisIt’s big-data capacity allows FieldView to handle a wider range of CFD visualization tasks. “But ‘if you want to turn it into a commercial product, you really have to spend the time to customize things to people’s workflows,’ Brugger says. ‘We’ve customized it to our workflows in the DOE community,’ but it doesn’t always fit other users workflows.”


ASCR recognized it needs help to move VisIt and other DOE-supported solutions for high-performance computing into commercial use. Through the SBIR program, it called
for small businesses able to take DOE codes and “shrink wrap” them into accessible tools.


The collaboration “shows DOE is taking its research and development and spawning new technology – which is one of our missions,” says Benjamin Grover, division leader for
Applications, Simulations, and Quality at Livermore.


With a Phase II grant of nearly $1 million, Intelligent Light is integrating VisIt into its FieldView HPC suite. Later this year, customers will be able to choose either the standard FieldView code or VisIt to visualize CFD data.

Interactive Exploration of High Fidelity ICE Simulations

Interactive Exploration of High Fidelity ICE Simulations

Learn how you can create and analyze ICE simulations with hundreds of time steps and hundreds of thousands of simulated particles.  Interactively explore your high fidelity data to improve understanding of your results.
Attend this webinar[1] by Intelligent Light and Convergent Science to see how you can escape current limitations and achieve more from your CFD.


An innovative transient post-processing approach for ICE simulations[2]


In the quest to improve simulation accuracy and fueled by the rise of HPC, simulations are being performed on ever finer meshes and with larger number of particles.  In the case of internal combustion engine CFD which requires very long transient runs in order to reach convergence, this has become problematic due to the huge amount of data and the time it takes to review it.
This presentation will describe, through an ICE case study simulated with CONVERGE, an innovative post-processing approach that allows interactive analysis of several hundreds of time steps, containing hundreds of thousands of simulated particles.


Combined with more traditional methods (transient animations, time history plots…), this interactive investigation technique will provide unprecedented insight to complex transient flows.

HPCWire: Revolutionizing Innovation: When HPC Meets Cloud

by Roger Rintala | May 5, 2014 3:00 pm

Looking for answers to your questions about cloud-based HPC?

Attend the HPCWire webinar “Revolutionizing Innovation: When HPC Meets Cloud” sponsored by Dell.


Where innovation in engineering and product development is the key to marketplace success, high performance computing is the key to accelerated innovation.  Cost-effectively leveraging limited resources is a challenge for which on-demand HPC in the cloud can be an effective tool when the engineering tools and workflow are designed for it.


Intelligent Light’s own Steve Legensky joins Intersect 360′s Addison Snell and Larry Smarr of Calit2 in this webinar hosted by HPCWire’s Nicole Hemsoth. Mr. Legensky uses real world examples to show the motivation, success criteria, methods, and results that make on-demand HPC a compelling investment for small and large organizations alike.

Concordia SAE Racing[1]

Concordia University Students are developing their vehicle for the 2014 SAE Supermileage competition.

The Concordia University team is busy finalizing their design, paper submission, and preparation for the SAE Supermileage Competition[2] to be held June 5-6, 2014.


The team is pursuing both simulation and physical testing, correlating results, and committing parts to manufacturing.  All the components are fabricated by the team members.


Good luck to the entire team!  Stay tuned for updates and to see the vehicle after the unveiling!
