Simcenter FLOEFD for NX

Simcenter FLOEFD for NX

CFD fully embedded in Siemens NX for fluid flow and thermal simulation


Simcenter FLOEFD for NX is the fastest and most efficient computational fluid dynamics analysis tool that is embedded into Siemens NX. It enables engineers to directly work on their CAD model for preparing and evaluating their Concurrent CFD simulation:


CAD integrated
Automated meshing
Robust convergence criteria
Streamlined workflows



NX-embedded CFD Simulation

CAD-embedded simulation enables engineers to conduct analysis in the same user environment as design.

Therefore, engineers can use the latest CAD geometry for analysis to conduct multiple design studies and evaluate how the modifications influence the performance of the design without the hassle of data translation or reapplying boundary conditions and material properties.


Parametric Study and Design comparison Functionality

The compare configuration and parametric study capability inside Simcenter FLOEFD enables engineers to understand the influence of changes in the geometry or boundary conditions on the results.

Users can evaluate the design envelope by assessing results by numerical values, by graphs and by visual images and animations and thereby compare a wide range of project permutations.


Fast and Automated Cartesian Meshing Technology

Simcenter FLOEFD uses Cartesian meshing technology which is recognized as the most efficient framework for simulating fluid flows, heat and mass transfer.

In addition, the meshing process can be automated easily for even the most complex CAD geometries. When coupled with an immersed boundary cut-cell approach, this form of preprocessing inside Simcenter FLOEFD gives unprecedented speedup in the overall design process.


LED and Lighting Thermal Simulation Capabilities

Simcenter FLOEFD's LED Module provides a unique range of capabilities required for lighting applications and types of lighting.

  • Combined thermal and photometric model for LEDs based on T3Ster measurements of actual off-the-shelf LEDs yields correct power and temperature predictions and "hot lumen" output
  • Its Monte Carlo radiation model is best suited for thermal radiation predictions in lighting applications where lenses or reflectors can cause deviations in focal points from the light source (solar or man-made)


Instinctive User Experience

Simcenter FLOEFD for NX features an easy-to-use GUI with considerable intelligent automation built-in as standard:

  • Operate within NX graphical user environment
  • Powerful analysis wizard guides users through the problem set-up
  • Interface uses engineering terms instead of technical jargon therefore users can focus on solving flow problems as opposed to figuring out how to use the software
  • Real-time feedback about the solution progress such as convergence, residual errors and monitor point values
  • Engineering outputs appear in both a timely and intuitive manner including reports in Microsoft ® Excel and Word
