FLOEFD for NX: An Introduction

By William Chanatry

FLOEFD for NX is an easy-to-use, fast and accurate Computational Fluid Dynamics (CFD) analysis tool that is fully integrated in NX. FLOEFD enables engineers to frontload simulation by moving CFD simulation early into the design process. This allows the design engineers to examine and evaluate design options earlier to obtain optimized product performance and reliability.

FLOEFD features intelligent automation at its core to make frontloading of CFD a reality:

• An intuitive user experience – short learning curve


• Use of native Siemens NX CAD data – no translation or fluid body creation

• Fast automated mesher – fast and easy SmartCell™ meshing

• Unique solver – getting accurate results fast for highly complex geometry

• Powerful parametric study and design comparison functionality for easier what-if analysis

Automatic recognition of model change – geometry and simulation data are synchronized FloEFD can be easily inserted into your current NX design flow without any disruption to your existing process and reduce your overall simulation time by as much as 75%.
