Simulation Made Simple
New EFD.Lab and EFD.V5 Version 5.1
NIKA has released the new version 5.1 of EFD.Lab and EFD.V5, which has been developed in close industrial
co-operation with Metzeler APS. EFD.Lab and EFD.V5 are simulation packages for flow and heat transfer processes,
and were specially designed for use in development and design departments.

NIKA’s innovative Engineering Fluid Dynamics (EFD) technology is the reason why fluidic analyses can be
performed directly on the design workstation as part of the product development process. EFD.Lab provides
one of the most modern pre-processors, featuring extensive parametric 3D solid modelling functionality and
high-quality direct interfaces to all leading CAD systems. EFD.V5 goes one step further, as it is seamlessly
integrated into the CATIA V5 PLM system from Dassault Systèmes. EFD.V5 works directly with the CATIA model
and uses the feature tree to access all data entered. A further crucial element of the Engineering Fluid
Dynamics concept behind EFD.Lab and EFD.V5 is the use of the mechanical CAD model for flow simulation without
having to derive the internal flow space separately as a component for grid generation.
NIKA’s New EFD Software
... automatically identifies all areas where a flow occurs and any components that are involved in heat transfer
and then uses Rectangular Adaptive Mesh technology to generate a high quality calculation grid, also fully
automatically. The simulation results are evaluated graphically and mathematically directly on the CAD model
using comprehensive post-processing functions, which provides an extremely clear three-dimensional representation
of the flow processes in or around the product. EFD.Lab and EFD.V5 allow a broad range of technical issues to be
simulated and provide numerous tried and tested physical models to achieve this. In the new version 5.1, as well
as improvements for rotating components and fans, these have been supplemented by a function for mixing liquids
with complicated flow characteristics. Such liquids include melted plastic and rubber, foodstuffs and many biological
fluids. The new mixing function has been developed and implemented in close co-operation with Metzeler Automotive
Profile Systems. Metzeler APS, the global leader in the development and manufacture of body sealing systems and
window channel technology, used its know-how of rubber extrusion to work jointly with NIKA to integrate an appropriate
calculation model for coextrusion of window sealing profiles for vehicles into EFD.Lab and EFD.V5 (Figures).

Interesting Applications
NIKA’s EFD technology now enables Metzeler APS to simulate the flows through the extremely complex extrusion
tools alongside their design. As a result they can obtain important information for tool optimisation. The new
mixing function also extends the simulation possibilities of the EFD product family to many new and interesting
applications such as processing chocolate, manufacture and packaging of ice cream and dairy products, extrusion
of plastics and flows in medical and laboratory equipment. Of course, all of the new functions have been implemented
in line with the strict principles of the EFD concept to ensure that NIKA’s simulation software meets the same high
requirements in terms of accuracy, efficiency, easy handling and low total costs.
