is a professional tool for fluid dynamics analysis. The mainstream MCAD system includes Pro/ENGINEER, CATIA, Siemens NX and SolidWorks, and is tightly integrated with Inventor and SolidEdge. FloEFD is a full-featured three-dimensional fluid flow and heat transfer analysis software, easy to learn and use, because it does not require users to handle mathematical complexity and grid generation problems in traditional high-end CFD software. It is widely used in military, aerospace, electronic communications, automotive, machinery, medical devices and other industries, and do not miss friends who need it.

Software introduction

FloEFD is a fluid dynamics analysis software for product design engineers. After years of theoretical and engineering practice, it has been verified that there are more than 3000 customers worldwide. FloEFD is a highly engineered universal fluid heat transfer analysis software that is seamlessly integrated into the mainstream 3d CAD software. It is developed based on the finite volume method (FVM) widely adopted in the mainstream CFD software nowadays. FloEFD fully supports all the mainstream 3d CAD models directly imported into Pro/E, Catia, Solidworks, Siemens-NX, Inventor and so on, and can import model files such as Inventor, x, C, C, C, C, C, C, C, C and so on. The analysis steps of FloEFD include CAD model establishment, automatic mesh generation, boundary condition exertion, solution and post-processing, which are all completed under the CAD software interface. The whole process is fast and efficient. FloEFD directly applies the CAD solid model, automatically determines the fluid area, and automatically meshes, and does not need to re model the fluid area. In doing CAD structural optimization analysis, first, a CAD model is defined by a FloEFD analysis. The CAD model of the same structure (assembly) only needs to apply the unique Project technology, so that the FloEFD calculation under different assembly can be carried out immediately, so as to optimize the design plan quickly.

software function

Easy to use synchronous CFD tool integrated in CAD system

When analysis becomes part of the design process, it must be easy to use and quickly adapt to your design process. FloEFD is specially designed for engineers and is fully integrated in CAD system for easy operation. FloEFD is a very easy-to-use tool because of its intuitive interface. In fact, most design engineers feedback that they can use FloEFD in less than 8 hours of training.

Software features

It is a general CFD software which is seamlessly integrated in CAD software and for structural design engineers. FloEFD distinguishes itself from the four advantages of traditional CFD software:

For cooked CAD soft Parts engineer

FloEFD is developed for engineers, so engineers only need very basic knowledge of fluid dynamics and heat transfer, and do not need more understanding of numerical analysis and fluid dynamics equations. They can complete fluid and heat transfer analysis in familiar CAD software interface.

Integrated into CAD in Easy to use

The interface of FloEFD software seamlessly integrated into the CAD environment is very intuitive and flexible, and new users generally need one to two days of training from entry to proficiency.

stay CAD Software Rapid analysis

By integrating the FloEFD analysis wizard in the CAD environment, engineers can complete the flow analysis of CAD models within a few hours. Therefore, in engineering practice, we can analyze many different schemes conveniently and quickly.

stay CAD Software direct Connection optimization

FloEFD can directly carry out the optimization analysis of different schemes in the CAD model. There is no need to establish the necessary fluid models in traditional CFD software (solid area Boolean partition, etc.), mesh generation, and apply boundary conditions to solve them.

Software superiority

One DC Three - Direct CAD-to-CFD Conception ( Direct embedding in 3D CAD software environment )

The pretreatment process of traditional CFD software first introduces the structural CAD model into the pre-processing system of CFD software, and then manually determines which areas are fluid flowing and which are physical areas, and then assists geometric modeling, and completes the cutting and deleting of entities by Boolean operations. The preparation of slightly larger models will take a long time. Because CAD structure engineers are different from CFD analysis engineers, geometric modeling work such as Boolean operations often fails. In this case, CFD simulation engineers will have to remodel a large number of parts of the model. The emergence of FloEFD software has brought great convenience to CFD analysis engineers, thanks to the seamless integration of FloEFD and mainstream CAD software, enabling FloEFD to:
Fully embedded CAD interface, directly use CAD model to automatically distinguish solid area.
Automatically distinguish fluid regions outside solids, automatically determine internal flow and external flow area.


2. RAM – Rectangular Adaptive Mesh (rectangular adaptive grid)

Grid partitioning is a key work in the traditional CFD software analysis, which is the most time-consuming and most demanding job for the analyst's professional background. The quality of mesh generation is directly related to the accuracy of the analysis results. The traditional CFD analysis engineers need to spend a lot of time to divide the high quality grid. However, this situation will be completely changed in FloEFD software. FloEFD's powerful grid automatic generation capability will liberate engineers from heavy grid work, because FloEFD can:
Automatically meshing the solid and fluid regions, and automatically refine and coarse-grained mesh according to geometric models and adaptive requirements.
Full support for manual grid control and local encryption.


3. MWF – Modified Wall Functions (modified wall function)

The partition of near wall boundary layer has always been an important part of traditional CFD software. FloEFD software has its own unique advantages for wall processing.
With Partial Cell technology, wall processing has nothing to do with mesh.
Physically modified flow and heat transfer boundary layer simulation


Four LTTM – Laminar-Transitional-Turbulent Modeling ( Strong laminar flow - transition - Turbulence simulation capability )
Automatic mesh modification is used to simulate laminar and turbulent flows.
Automatic determination of laminar flow, transition zone and turbulent area without specifying the flow characteristics.


5. ACC – Automatic Convergence Control (automatic convergence control)
Cutting-edge numerical method and multigrid technique are used.
Stable convergence and reliable solution.
The solution is successful, and the value is false diffusion.


6. DVA – Design Variants Analysis (variable design analysis)

It allows variable simulation of product design and can be used to determine the optimal variables in product design.
