VisIT Prime

Integrated, Affordable Uncertainty
Quantification for CFD

SpectreUQ™ builds on the mature and sophisticated DAKOTA software from Sandia National Laboratories and adds a wizard to guide the engineer through the UQ process.The details of the disciplined UQ process are handled behind the scenesIt uses a database to store results from experiments and simulations in a structured fashion and provides interactive graphing and visualization tools.

UQ is one of the most important gaps in computational fluid dynamics(CFD) simulation capability, and is essential for being able to identify confidence levels forhypersonic CFD simulations.

Features & Benefits

Wizard-based User Experience

Easy to learn and use, tuned over hundreds of hours of use on actual UQ studies. The Oberkampf-Roy method is used to guide the process of ingesting experimental data and CFD results. Interactive plots of results are easy to explore and publish.

Simulations can be run on-line or off

SpectreUQ™ analyzes the inputs of your study creates a run matrix for CFD that can be used to run your codes directly or provide you with input decks so that you can run simulations yourself. Minimizes job management and IT security hassles.

Campaign data organized in SQL database

Using a combination of an SQL database with a LINUX file system gives searchable metadata for the current and future studies while providing secure storage for sensitive data.

Affordable

Provided via an annual subscription without user count restrictions and in source code form.

Non-invasive

SpectreUQ™ unlike other methods, is non-intrusive to the simulation; it runs alongside the code not within it.

Scalable

Using your own HPC, you are free to evaluate 100’s of flight conditions to train built-in surrogate models.

Domain Experts

For years our team has worked with DAKOTA & Sandia, done research with leaders in UQ and presented/published.

Why Choose Us?

Our team & technology are built on 27 years of experience and inspiration serving the CFD community via FieldView & Applied R&D. We spun off FieldView in 2019 so that we could focus on helping the community move their analysis into the 21st century.

Contact us for a web-based briefing and let’s see how we can possibly help you achieve your goals. We can define a pilot project that provides value to you and starts our collaboration. We can then explore subscription-based options right sized for you.
