New Software: SRAC Introduces COSMOS/FloWorks
Posted Wed May 01, 2002 @05:40PM
Print version Email story Tweet story
News Structural Research & Analysis Corp. (SRAC), developer of COSMOS/Works, the best selling design analysis program for SolidWorks users, today introduced COSMOS/FloWorks, a computational fluid dynamics software powered by NIKA's popular flow simulation technology.

The only fluid dynamics program that is fully embedded within the SolidWorks user environment, COSMOS/FloWorks provides design engineers with a fundamental analysis of the flow of gases and liquids, heat transfer, and other forces on immersed or surrounding solids. The same qualities that make SolidWorks the industry's leading mid-range CAD system for the design of engines, valves, hydraulics, piping, pumps, HVAC, and other complicated assemblies make COSMOS/FloWorks the perfect tool for analyzing them.

COSMOS/FloWorks ignores the traditional practice of handing off fluid analysis to specialists by translating problems into engineering analysis goals rather than numerical convergence criteria and solver parameters. Leaving the SolidWorks geometry as a solid model, COSMOS/FloWorks empowers engineers who are not analysis experts to succeed in today's design environment.

New Software: NUMECA Releases FINE/Design3D

News Numeca has released FINE/Design3D, a software tool for the design and optimization of innovative, efficient 3D blade shapes. Multi-parameter user-defined objective functions are used to define design performance targets while meeting geometrical and mechanical constraints.

FINE/Design3D includes Autoblade and Design3D.

Autoblade is a versatile parametric blade modeler for accurate representation of all types of turbomachinery blades and channels. Geometry definition is generic (Pressure/Suction side or Camberline/Thickness) and highly flexible (independent control of the tangential and meridional lean and sweep, multiple choices for the 3D blade stacking, multiple splitters, rounded or cut-off leading and trailing edges with tailored shapes…).

Design3D is a powerful and integrated optimisation process for turbomachinery applications. Through a comprehensive interface, customised to the turbomachinery design industry, an optimisation loop is performed that includes:

  • A self-learning database that stores the parameters of the optimisation runs;
  • An optimization step with gradient, simulated annealing and genetic algorithm methods.

Optimisation targets can be linked to local and global features of the flow field, while geometrical constraints can limit the solution domain.

New Software: CFdesign for SolidWorks
Posted Tue April 30, 2002 @05:58PM
Print version Email story Tweet story
News Blue Ridge Numerics has announced that its CFdesign® multi-purpose fluid flow and heat transfer simulation software is now available as an integrated add-on application for SolidWorks.

CFdesign makes it possible for 3D product designs built in SolidWorks to be evaluated and optimized without any type of translation or conversion process. Changes made to geometry within SolidWorks are automatically reflected in CFdesign, eliminating the time-consuming and confusing process of creating and managing multiple geometry models during a project lifecycle. With CFdesign there is always only one model, and it is updated and managed within the SolidWorks environment.

“We believe the global SolidWorks user community is starting to come of age where design analysis is concerned. The value proposition is just too great to ignore,” stated Blue Ridge Numerics President, Ed Williams. “We consistently see our customers increase product quality and strip away costs while bringing products to market faster than ever before when CFdesign is used hand-in-glove with an MCAD system on the mechanical engineer’s desktop PC.”

When SolidWorks users launch CFdesign directly within the SolidWorks interface, the component or assembly will automatically appear inside CFdesign where comprehensive fluid flow and heat transfer simulations can reveal product performance concerns and identify areas for product optimization.

Application: CFD Leads to Successful Design of Gas-Fired Preheater
Posted Mon April 29, 2002 @05:22PM

ANSYS FLUENT by Serguei Nester, Principal Combustion Engineer, and Joseph Rabovitser, Assistant Director
Gas Technology Institute
Des Plaines, Illinois

Computer simulation saved more than $100,000 dollars in the design of a new coal preheating technology for low NOx burners by making it possible to get the design right the first time. The Gas Technology Institute (GTI) is developing a NOx reduction process under a cooperative agreement with the Department of Energy to provide a cost effective, combustion-based alternative to selective catalytic reduction (SCR). Development targets include NOx reduction to below 0.15 pounds per million Btu, reduced CO2 emissions, and a 55% electricity cost reduction compared to SCR. The technology combines GTI’s Methane de-NOX reburn technology with a pulverized coal (PC) preheating approach developed for utility pulverized coal combustors by the All-Russian Thermal Engineering Institute (VTI). Many variations of the initial burner design were evaluated using computational fluid dynamics (CFD), making it possible for engineers to determine an optimized design concept. As a result, the initial prototype met the design objectives, eliminating the need to build and test additional prototypes at a cost that would have probably run into six figures each.
