CPFD: Computational particle fluid dynamics

Computational particle fluid dynamics denotes a category of numerical and computational techniques for solving equations of fluid dynamics in which the fluid continuum model is replaced by a finite set of particles. The pioneering developer of these methods, and of commercial software that encapsulates them, is CPFD Software LLC.

“Unequalled accuracy in modeling particle flows”

CPFD describes its mission as “advancing the state-of-the-art in a large but underserved CFD simulation market segment” by building on its proprietary physics-based simulation technologies to “virtualize the chemically reacting particulate flow dynamics of fluidized reactors across all industries, and delivering game-changing economic improvements in output, efficiencies, time-to-market and emissions compliance.”

The company says its clients in senior management “appreciate the cost savings that Barracuda,” its flagship software offering, “can generate for a relatively small investment, and engineers appreciate the competitive edge it provides by revealing scientific insights unavailable with other software.”

The company characterizes Barracuda as “unique among CFD technologies because it was designed exclusively for one purpose: to model particulate-solid flows in fluidized systems. Unlike familiar codes such as ANSYS Fluent, Siemens STAR-CCM+, OpenFoam and others who gradually modified single-phase CFD methods in an attempt to model particle flows, the Barracuda engineering software package was built from the ground up, based on the firm foundation of the multiphase-particle-in cell (MP-PIC) description of the particle phase with strong coupling between fluid and particle phases.”

As a result, the company says, its software “delivers an unequaled level of accuracy that translates to economic value and a competitive advantage” by:

  • Avoiding costly reactor shutdowns and repairs.
  • Lengthening equipment lifecycles.
  • Increasing production of reactor products and yields.
  • Reducing emissions.
  • Ensuring success of scale-up operations.
  • Predicting performance without prototype investment.

“Launching the Simulation Revolution”: Dimitri Mavris of Georgia Tech to keynote ASSESS 2018 Congress

The ASSESS Initiative, says CEO and cofounder Joe Walsh, is “a broad-reaching multi-industry initiative to facilitate a revolution of enablement that will vastly increase the availability and effectiveness of engineering simulation.” Walsh and the Initiative just announced that Dimitri Mavris, S.P. Langley NIA Distinguished Regents Professor with the Georgia Institute of Technology, will keynote the ASSESS 2018 Congress, scheduled for October 28-30 in Braselton, GA. At the Congress—in our view, the single most important annual gathering of technology consumers and providers alike in the world of engineering modeling and simulation—Mavris will speak on “The Creation of a Digital Twin of the Georgia Tech Campus.”

“I am very pleased to be able to share information about the active project to build a systems-based digital twin of the Georgia Tech campus,” Mavris said, “and look forward to engaging discussions on future directions of systems modeling and digital twins.” Mavris is the Boeing Chaired Professor of Advanced Aerospace Systems Analysis in Georgia Tech’s School of Aerospace Engineering, Regents Professor, and Director of its Aerospace Systems Design Laboratory (ASDL). Continue reading 

SIMSOLID Cloud: Breakthrough no-meshing, no-defeaturing structural analysis tool now available as an Onshape-enabled cloud application

SIMSOLID, first rolled out in 2015, is a structural modeling and analysis software application that radically democratizes FEA by working directly on imported CAD geometry with no need for the two most time- and labor-intensive aspects of traditional structural analysis tools: CAD geometry simplification, or de-featuring, and finite-element mesh generation.

“Announcing SIMSOLID Cloud: Popular desktop structural analysis tool now available as an Onshape-embedded cloud application”

In February, SIMSOLID Corporation announced the general availability of SIMSOLID Cloud. SIMSOLID’s positioning of the product is that it “continues to set the standard for rapid simulation-driven design. Its innovative core technology eliminates geometry simplification and meshing, the two most time-consuming and expertise-extensive tasks done in traditional FEA. Moreover, SIMSOLID can analyze complex parts and large assemblies not practical with traditional FEA and provides performance feedback in seconds to minutes.” Our firsthand research among early adopters firmly confirms those claims. Continue reading

Lensing 2020 and beyond: 8 megatrends in engineering modeling and simulation

This second decade of the twenty-first century is witnessing an explosion of invention and innovation in digital engineering technologies unrivaled since the 1980s, when so many foundational tools and methods were either created or brought to practical fruition. Here are eight megatrends that we believe will drive generational leaps forward in engineering modeling and simulation technologies, methods and work processes through 2020 and well beyond:

  • Simulation-led, systems-driven product development.
  • Democratization of engineering modeling and simulation.
  • Simulation app revolution.
  • Design space exploration.
  • Topology, materials and process optimization for additive manufacturing.
  • Simulation for the Industrial IoT and Industry 4.0.
  • Big-data analytics in simulation.
  • Cloud HPC for simulation.

Already, each of these is today the focus of intense development by technology providers—and of investigation, investment and, in many cases, deployment by leading engineering organizations. Much of this work is succeeding in at last transforming long-established, powerful but formerly difficult-to-use, specialist-user-only tools into practical everyday engineering aids. And some of it—rather a lot, actually—is giving engineering organizations capabilities never before possible. Continue reading

New EDEM/RecurDyn co-simulation solution gives off-highway equipment engineers high-fidelity modeling of bulk material behaviors

Bulk-material simulation specialist EDEM released a co-simulation solution between its software and RecurDyn, the multibody dynamics modeling and simulation toolset from FunctionBay. This new integration enables engineers designing heavy equipment such as excavators, ploughs and off-road vehicles to introduce realistic bulk-material behaviors into their multibody dynamics simulations. EDEM says the new technology offers heretofore unrivaled insight into how material loads are transferred throughout the product’s structure and systems, and provides engineers with essential insights into equipment/material interactions.
