FloEFD for NX/Simcenter 3D applications for modeling flow and heat transfer in liquids and gases in an appropriate CAD environment.


FloEFD is fully integrated into the respective CAD environment and uses solvers based on computational fluid dynamics (CFD) technology
Main advantages
For CAD-dependent versions, work directly with the model in the corresponding CAD environment

There is no need to convert the geometry to another format, which often leads to a loss of quality The task of calculating fluid dynamics and heat transfer is fully synchronized with the
model at any time
There is no need for “manual” construction of geometry describing the area occupied by liquid / gas
Automatic detection of the area occupied by liquid/gas.
The same graphical controls are used as in other modules of the respective CAD
Very easy to learn
Easy to use
Uses a tree of CAD model elements.
Intuitive and fully interactive
Use of model elements selected in the graphics window/model tree when creating a project/results processing
Visualization of calculation results in the form of static and animated images directly in the graphics window
Support for exporting results to MS Excel, Word. Ability to play and record animation
Support for multi-configuration of the model
For effective multi-parametric research, the ability to clone projects, automatic start of a series of calculations are implemented.
Automated to reduce the number of cases when analysis of the setup and calculation results requires the involvement of specialists in the field of fluid dynamics and heat transfer
Reliable and fully automatic grid generator
Uses a unique turbulence and boundary layer model
Automatic control of solution convergence.
Reliable and accurate numerical methods and physical models
Large set of physical models
Exact solution
Ability to calculate very complex structures and physical phenomena.
