Fluent Inc., Aspen Technology, Inc. (Nasdaq: AZPN), and Enductive Solutions, Inc. announced today the availability of a powerful standalone toolkit that interfaces FLUENT®, the world’s leading computational fluid dynamics (CFD) software for detailed flow analysis of process equipment, and Aspen Plus®, the leading process modeling software for the chemical, petrochemical, pharmaceutical, and power industries. The integration of CFD and process simulation enables companies to better understand and optimize the fluid mechanics that drive overall process performance and efficiency.

CFD is a vital technology for simulation, visualization, and prediction of fluid flow, heat and mass transfer, and chemical reactions. It is a critical part of the computer-aided process engineering (CAPE) lifecycle for manufacturing companies around the world. Throughout the process industries, Fluent's CFD simulations are delivering major business benefits by enabling engineers to design for better equipment performance, more effective scale-up, improved safety, and higher productivity.

The development of the integrated software tools were funded in part by the Department of Energy's Office of Fossil Energy to be used to simulate and visualize advanced plant concepts in support of the DOE's Vision 21 program. The National Energy Technology Laboratory sought a solution to integrate power-plant process simulation with detailed plant component software to meet DOE's goal of modeling the performance of these complex systems.

The integration toolkit, which enables FLUENT 6.1 to be used with the recently released Aspen Plus 12.1, uses the process-industry CAPE-OPEN interface standards for unit operations, physical properties, and reaction kinetics, so that all integrated designs and analyses are based on consistent and complete data. Enductive Solutions, through its partnership with Fluent, is offering this integration toolkit as well as comprehensive services designed to help customers deploy coupled CFD and process simulation as part of a complete engineering solution.

“We are very pleased to be partnering with AspenTech, who is the market leader for engineering software and solutions in the process industries,” notes Barbara Hutchings, Fluent’s Director of Strategic Partnerships. “Our customers require this kind of interoperability in order to see how individual process equipment items impact overall plant behavior, and the coupling of these best-in-class tools is part of our overall strategy to deliver this capability. With Aspen Plus and FLUENT our clients get the power of process simulation with the detailed analysis of CFD.”

“Accurate process simulations are critical for enabling our customers to develop superior plant designs and to optimize existing plants”, says Manolis Kotzabasakis, Sr. Vice President of Engineering at AspenTech. “We are excited to be providing the first comprehensive ability to use rigorous CFD models in process simulations, and to be collaborating with Fluent to make this a reality for Aspen Plus 12.1 users. The new interfacing capability provides significant benefits across the lifecycle of plants designed and operated in the process industries.”

ALSTOM Power is one of several companies that played an advisory and applications role in the development of the FLUENT-Aspen Plus toolkit. To demonstrate the utility of the toolkit, ALSTOM Power used it to model a conventional steam power plant and an advanced natural gas combined cycle power plant. "We are very enthusiastic with the results of the Fluent and Aspen Technology collaboration," said Dr. Woodrow Fiveland, Director of Combustion and Environmental Technology at ALSTOM Power. "We expect significant benefits from knowledge reuse as the new interface fosters communication between the CFD analysts and the process simulation experts in our company."

About Enductive Solutions

Enductive Solutions (http://www.enductive.com/) has the mission of helping its clients use computer-aided engineering (CAE) in the smartest way possible, thus shortening their product development cycles, decreasing time-to-market, and reducing costs overall. Partnering with the client, they create a solution approach, which focuses on applicability, simplicity, ease-of-use, and integration. The approach considers the client's internal expertise, existing design software, associated databases, and overall design process. The deliverable is often a customized graphical user interface (GUI), which ties together all the design components and the specific tools and hardware in the process, so that time is saved, tedium is reduced, and integration is achieved. The outcome is a custom, focused, customer-tuned CAE process, which is ideally suited to the client. The firm makes use of a large Solution Alliance Partner network to aid in fast implementation of client solutions.
