FloEFD for NX/Simcenter 3D application for modeling flow and heat transfer in liquids and gases in the environment of the corresponding CAD system.


FloEFD is fully integrated into the environment of the corresponding CAD systems 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 into another format, which often leads to a loss of quality. The stated task of calculating fluid dynamics and heat transfer is completely synchronized with the model at any time.
Minimization of efforts, and as a result, errors in the process of synchronizing the stated fluid dynamics problem and the model.
Automatic detection of changes in the model.
There is no need to “manually” construct geometry describing the area occupied by liquid/gas
Automatic detection of the area occupied by liquid/gas.
Uses the same graphical controls as other relevant CAD modules
Very easy to learn
Easy to use
Uses CAD model tree.
Intuitive and fully interactive
Use of model elements selected in the graphic window/model tree when creating a project/processing results
Visualization of calculation results in the form of static and animated images directly in the graphic 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-parameter research, the ability to clone projects and automatically launch a series of calculations are implemented.
Automated to reduce the number of cases when it is necessary to involve specialists in the field of fluid dynamics and heat transfer to analyze the formulation and calculation results
Reliable and fully automatic grid generator.
A unique turbulence and boundary layer model is used.
Automatic control of solution convergence.
Reliable and accurate numerical methods and physical models
Large set of physical models
Accurate solution
Ability to calculate very complex structures and physical phenomena.
