NIKA Announces EFD.Lab 3.1

New Gas Flow Solver and Geometry Optimization Tool in addition to Floating License Support Increase Efficiency

Frankfurt, Germany (March 26, 2003) --- NIKA today announced the availability of EFD.Lab 3.1, the latest release of its hottest selling stand-alone fluid flow and heat transfer simulation program. Among the new improvements are the addition of a powerful gas flow solver, a geometry optimization tool and floating license support. “With this new version, NIKA increases Engineering Fluid Dynamics simulation efficiency to an even higher level,” stated Roland Feldhinkel, NIKA’s managing director. “As a result, EFD.Lab is now better designed to meet the demanding needs of design cycle integrated fluid flow and heat transfer simulation.”

New Functionality Added
EFD.Lab 3.1 features many new improvements. Among them is the new solver for gas flows. EFD.Lab can now simulate gas flows ranging from low-Reynolds incompressible flows up to highly compressible supersonic flows including special physical effects such as shock waves without any user interaction. This new gas flow solver employs sophisticated numerical technologies such as multigrid algorithms for unsurpassed solver stability, convergence efficiency, solver speed and result accuracy.

In addition, EFD.Lab 3.1 can now perform automated geometry parameter computations to meet criteria defined by fluid flow effects. For instance, this tool can be used to compute the position of a valve piston acting against a spring using the balance between the forces on the piston induced by fluid flow and the valve’s spring force.

Finding optimal positions of parts within an assembly meeting defined flow criteria, or computing the shape and size of geometry details like fillets or openings for better flow design could be among other applications of this new capability.

A floating license option has also been added for the latest release of EFD.Lab. This option allows the flexible use of multiple seats of the software within a network setup independent from specific workstations.

Design Cycle Integrated Fluid Flow Simulation with EFD.Lab
EFD.Lab is based on the principles of Engineering Fluid Dynamics (EFD). EFD is a radically different approach from Computational Fluid Dynamics (CFD). While based on the same mathematical foundation as CFD programs, EFD programs are not only powerful, but also extremely easy to use.

EFD.Lab features incompressible (liquid or gas) or compressible (gas) flows, laminar, turbulent, steady-state and transient flows, surface roughness, conjugated heat transfer, particle tracking, and many more physical models.
EFD.Lab is mainly used for the development and optimization of various products such as automotive parts, computer housings, switching units, electronic devices, HVAC systems, valves and regulators, medical equipment, in addition to the building and fire protection industries. EFD.Lab includes a preprocessor with parametric solid modeling of the geometry, and a powerful postprocessor for easy processing and visualization of results. The preprocessor imports native CAD files from the most important CAD systems and supports numerous standard file formats. The CAD geometry of a design can be directly used without modeling a separate domain of the flow space. This unique feature combined with automatic mesh generation and solver convergence controls allow the engineer to take advantage of fully integrated flow simulation within the design cycle.

About NIKA
NIKA GmbH was founded in 1999 and specializes in development and marketing of simulation software for fluid flow and heat transfer (Computational Fluid Dynamics). NIKA GmbH is a worldwide operating company with headquarters in Frankfurt am Main, Germany. EFD.Lab is distributed by authorized NIKA sales partners in Germany, France, Italy, Benelux, Spain, Scandinavia, USA and Japan. NIKA is actively looking for additional qualified distribution partners worldwide.
