Uncle Sam’s HPC CFD Post-processing Supercomputer specifies EnSight

When the U.S. Government’s Department of Energy (DoE)  builds its next two supercomputers, the Trinity and NERSC-8,  it specified the software for post-processing and visualization it wants to be able to use.  In that specification the only commercial software for post-processing was CEI’s EnSight.   See section 4.1.1 of the document for yourself.


These computers are to be delivered in 2015, probably not taking advantage of free shipping from Amazon Prime accounts, or iTunes gift cards.

No other agency in the world has built more supercomputers for science and engineering.  So at CEI, (we might be biased) we think it is a very strong endorsement for EnSight over other commercial CFD post-processing and visualization software.

The labs that will be using these computers are:


More nuggets from the introduction of the draft requirements document.

“The intention is to choose a single vendor to deliver two systems of similar technology. The technical specifications in this document describe joint requirements everywhere except for the tables in Section 3 that describe requirements specific to the Trinity and NERSC-8 systems.”  “The Offeror must respond with a configuration and price for both systems.”   Kind of like the Joint Strike Fighter procurement where the government didn’t want to buy different aircraft for different branches of the military.

“In the 2015 timeframe, the current ASC systems will be nearing the end of their useful lifetime.” “The Trinity system, to be sited at Los Alamos, NM, is projected to provide a large portion of the ATS resources for the NNSA ASC tri-lab simulation community: Los Alamos National Laboratory (LANL), Sandia National Laboratories (SNL), and Lawrence Livermore National Laboratory (LLNL), during the 2016-2020 timeframe.”

“The system needs to provide a significant upgrade in computational capabilities, with a target increase between 10-30 times the sustained performance over the NERSC-6 Hopper system.”

“In addition to increasing the computational capability available to DOE computational scientists, the system also needs to be a platform that will begin to transition DOE scientific applications to more energy-efficient, many-core architectures. This need is closely aligned with the US Department of Energy’s 2011 strategic plan, which states an imperative to continue to advance the frontiers of energy-efficient computing and supercomputing to enable greater computational capacity with lower energy needs. Energy-efficient computing is a cornerstone technology of what has been called exascale computing and represents the only way of continuing NERSC’s historic performance growth in response to science needs.”

Attempting to Break the Land Speed Record with the Help of CFD

CEI, Pointwise and North American Eagle (NAE) will present a free joint webinar on the application of computational fluid dynamic (CFD) techniques toward breaking the land speed record on Wednesday, November 7th at 11:00 a.m. CST. The webinar will be hosted by Chris Sideroff from Pointwise, Darren Grove from NAE, and Kevin Colburn from CEI.

Metacomp CFD++ solution of the North American Eagle @ 700 MPH with design cycle 1 fairings. Composite image showing unstructured viscous mesh generated with Pointwise, overlaid by stream-wise velocity on ground & symmetry planes, vehicle surfaces colored by pressure and near surface streamlines using EnSight post-processing software.

Aerodynamics Engineer Darren Grove will show us how use of Pointwise for pre-processing, CFD++ from Metacomp Technologies for flow solutions, and EnSight from CEI for post-processing NAE improved the drag and stability characteristics of the NAE vehicle. Within the context of the overall goal of achieving 800 mph, this webinar will discuss how Mr. Grove used Pointwise and EnSight to help design aft suspension fairings to reduce overall drag on the NAE car while maintaining stability and control.

Techniques presented will include:

• Generating fast, repeatable, complex, viscous, unstructured meshes with T-Rex
• Employing CFD as a cost-effective tool to help an all-volunteer team attempt the world land speed record
• Challenges of designing a stable, low drag wheel system for a supersonic ground vehicle
• Efficiently extracting drag and stability information from a large number of calculations using EnSight

The purpose of the North American Eagle™ Land Speed Program is to test the capability of a land based vehicle to safely transition through supersonic speed. The by-products of this challenge have the potential to impact high-speed rail, ground effects of high-speed aircraft in the landing configuration as well as deceleration methods utilized by high-speed vehicles. The fuels and lubricants utilized during the project are also significant. Materials used for the construction of the vehicle, and most importantly, the wheels, are critical to the project’s success. All phases of this project are continually measured against a risk factor. Above all, breaking a land speed record must not result in unacceptable risk to the driver, crew or spectators. The primary objective of the project is to break the current land-speed record of 763mph, currently held by the British, with the goal to get to 800mph.

River Flooding, Tsunami and Groundwater Simulations

We’ve noticed a surge in interest in EnSight for visualizing flooding and other groundwater control simulations.

Yes, we do have translation routines for both River-FLO, FLO-2D, MIKE21_FM, and MIKE21_Classic formats. These translation routines to convert these formats into EnSight Case Format, which can then be read into and visualized with EnSight.

Summary of the different translation routines on our Python Exchange Website:

You can find details about the different translation routines, some examples of aerial photo application onto the model, special time annotations, as well as a video tutorial showing one of the translation routines in action, as well as some of the fundamental benefits of utilizing EnSight for visualization of these types of river & flood tools.

You can also find on our gallery website some of the animations and engineering quantification of River & Flood simulation results using EnSight:

Keyframe animations, aerial photo texture mapping, isovolume calculation, graphs of the area effected over time, max depth, as well as profiles through the simulation.


This short animation illustrates the power of EnSight’s interactivity. In this video, we have first created a clip through the flood as a “cross-section”. We then graphed the depth along this cross section in the plotter. Next, the interactivity of EnSight now allows the user to interactively drag the cross-section to anywhere they would like, and the plot automatically updates instantaneously. Simulation results courtesy of Wood Rodgers.


Animation of the river flood event in EnSight. In this animation, we have used EnSight’s 3D arrow along with the interactive query of the max depth to illustrate to the user the dynamic location of the maximum depth as time develops. Simulation results courtesy of Wood Rodgers


Are you involved with River and Flooding simulations? Are there specific aspects to the simulation that you are trying to capture and illustrate? We’d like to hear more about this type of work and see where EnSight can help you analyze, visualize, and communicate those results.
