FloEFD for NX is an application for modeling flow and heat transfer in liquids and gases in a CAD environment.
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, working directly with the model in the corresponding CAD environment
There is no need to convert geometry to another format, which often leads to a loss of quality.The task of calculating fluid dynamics and heat transfer at any time is fully synchronized with the model
Minimization of efforts, and as a result, errors in the synchronization process of the set fluid dynamics problem and the model
Automatic detection of changes in the model.
There is no need for “manual” construction of the geometry describing the area occupied by the liquid / gas
Automatic detection of the area occupied by liquid / gas.
The same graphical controls are used as in other corresponding CAD modules
Very easy to learn
Easy to use
Uses the CAD model tree.
Intuitive and fully interactive
Use when creating a project / processing results of model elements selected in the graphics window / model tree
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. The ability to play and record animations.
Support for the multi-configuration model.
For effective multi-parameter research, the following features are implemented: the ability to clone projects, automatically start a series of calculations.
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 generator of computational grids
A unique model of turbulence and boundary layer is used.
Automatic control of the convergence of the solution.
Reliable and accurate numerical methods and physical models
Large set of physical models
Exact solution
Ability to calculate very complex structures and physical phenomena.
