Chief Scientist

DoD High Performance Computing Modernization Program


Create program concept l.jpg

CREATE Program Concept

  • Enable major improvements in the acquisition process

    • Prevent defects and design flaws early in the acquisition process

    • Reduce rework thereby enabling faster system deployment

  • How?

    • Inject multi-physics based predictions early within the design and analysis process

    • Develop and deploy production quality design and analysis software that is adaptable and maintainable

    • Develop and deploy multi-physics based Computational Engineering tools that exploit next generation computer resources

  • CREATE is a multi-year program, funded at $40M to date

    • Funding started in FY2008

    • Initiated by USD(AT&L) in 2008

Path forward l.jpg

Path Forward

  • DoD has an opportunity to substantially reduce product development time

    • Requires adoption of multi-physics based software design and analysis tools by both government and industry

  • We don’t have a lot of insight into how these products can move into industry

    • Council on Competitiveness studies document that industry has been slow to adopt multi-physics software

  • How do we make this happen?

(Many) Design iterations

F-22 Flight Test

  • Long time to deployment

    • Requires many lengthy and expensive design/build/test iteration loops

    • Process converges slowly, if at all

    • Design flaws discovered late in process


A paradigm shift in product development is underway l.jpg

A Paradigm Shift in Product Development Is Underway

  • Past :

    • Repeated DesignBuildTest Cycles

  • Present:

    • Occasionally Augment DesignBuildTest with Limited Single-Physics Analysis by Use of Research or Commercial Codes

  • Future:

    • Design Through Analysis, Multi-Physics Design and Analysis with Supercomputer Power

    • Repeated CADMeshAnalyze Cycles Followed by a Few DesignBuildTest Cycles

Physics-based Engineering Software Helped The US Win Cold War.

  • Nuclear weapons are complex, expensive, and hard to test

    • ~ 5 to 10 tests per system

  • DOE NNSA uses computational tools for:

    • Design development, optimization, & analysis.

  • DOE NNSA labs own the biggest supercomputers


Critical factors for success l.jpg

Critical Factors for Success

  • We analyzed what worked and what didn’t

    • Must have a lot of experience in computational engineering

    • Must have the right people—especially team leaders who have demonstrated that they can succeed

    • Must have highly skilled and experienced multi-disciplinary team

    • Must have stable support

  • We applied these principles to CREATE


The create approach l.jpg

The CREATE Approach

  • Software is being built by government-led teams

  • Each product has a roadmap

    • Each year there is a release of a usable application

    • Each release builds on the previous release and adds the increased capability called for in the roadmap

    • Each release is beta-tested by targeted user communities before production release

  • Releases are scalable for massively computers and responsive to user requirements

  • Users can access the applications, but we don’t plan to release source code

Early Success: Rapid Deployment of EP-3E

  • Shadow-Ops: CREATE staff use computational tools to support acquisition programs  provide experience and establish connections and value

  • Performed CFD analysis of impact of electronic countermeasure pod for EP-3E flight clearance--Not sufficient time for conventional process (flight tests)

    • Eliminated construction cost of wind tunnel model and tests and need for contractor flying quality report.

    • Provided aircraft flying qualities characteristics within required time frame.

    • Provided data required to issue flight clearance in time for direct deployment.

  • Reduced overall program cost and time.

  • Only 1 flying qualities flight test required – Saving between 3-4 flight tests.

  • System was deployed in the forward theatre in less than four months instead of twelve

Improved flight certification process for marine corps uav l.jpg

Another Early Success

Improved Flight Certification Process for Marine Corps UAV

8 foot wingspan

Engineers: Drs. Theresa Shafer / Gary N. McQuay - PMA-263 STUAS/Tier II UAS

  • Problem: Expensive and lengthy UAV flight certification for small-vendor designs due to physical testing required for flight data.

  • Solution: Joint Navy and CREATE Air Vehicles Shadow-Ops STUAS project used computational engineering tools to rapidly and cheaply develop the flight certification database.

  • Benefits to DoD Aircraft Programs

    • Reduced time and cost by eliminating the need for physical model testing

    • Enabled industry competitiveness through quick Services assessment of many vendor designs

    • Provided unbiased performance data to STUAS Program Office for assessment of contractor vehicles

  • Six new vendors are now able to compete for UAV contracts
