SpectreUQ vs. Dive

SpectreUQ™ significantly enhances the sophisticated DAKOTA software developed by Sandia National Laboratories by introducing a user-friendly wizard that supports engineers throughout the uncertainty quantification (UQ) workflow. The complex aspects of the UQ methodology are efficiently managed in the background, allowing users to focus on results. It utilizes a structured database to organize outcomes from experiments and simulations, while also providing robust interactive visualization and graphing features. Offered via an annual subscription with no user limitations, it is also accessible in source code form for customization. Unlike many traditional methods, SpectreUQ™ functions in a non-intrusive way, enabling it to operate alongside pre-existing simulations without requiring direct integration. Users can take advantage of their own high-performance computing systems to evaluate various flight conditions and create built-in surrogate models. The design prioritizes intuitiveness and usability, having been improved through extensive practical applications in UQ research. The integration of experimental data and computational fluid dynamics (CFD) results is facilitated by the established Oberkampf-Roy method, ensuring a reliable and systematic approach. Furthermore, the interactive plots produced aid in the exploration and dissemination of results, promoting collaboration and effective communication among engineers. This extensive functionality positions SpectreUQ™ as an indispensable resource for engineers aiming to incorporate UQ into their standard practices, ultimately enhancing the reliability and efficiency of their analyses.

Dive CAE is an advanced cloud-based platform tailored for computational fluid dynamics, enabling engineers to effectively model complex phenomena such as free-surface flows, multiphase interactions, heat transfer, and moving machinery dynamics using a mesh-free Smoothed Particle Hydrodynamics method. This software can be accessed via any web browser, eliminating the reliance on local hardware or installation, and is optimized for high-performance computing environments. The innovative mesh-free technique allows for intricate geometries to be modeled, effectively managing surface tension, accommodating non-Newtonian fluids, and handling transient flow scenarios without the extensive meshing requirements often associated with conventional CFD approaches. Users can quickly familiarize themselves with the software, typically within a single day, and it is engineered to support parallel design-of-experiment workflows, enabling a multitude of iterations to be completed in mere hours rather than several days. Dive CAE emphasizes user collaboration and features a user-friendly licensing model (one license covers all), promotes transparent cost management, adheres to data usage regulations, and offers scalability through its cloud infrastructure, making it a compelling option for engineering teams aiming to advance their fluid dynamics simulations. This blend of functionalities not only simplifies the simulation process but also enhances collaborative efforts, ultimately driving innovation and efficiency in project management. Furthermore, as engineering challenges become increasingly complex, platforms like Dive CAE are essential in providing the tools necessary for effective analysis and design.
