FloEFD – Flow simulation made simple and effective

Flow simulation in FloEFD

Are you having challenges dealing with heating of electrical components, aerodynamic drag or cavitation in pump or piping design? Is your product’s performance somehow affected by the fluid flow around or inside it? You might want to optimize the fluid flow and heat transfer in the product to maximize the performance.

This can be laborious and difficult, depending on how good you are with fluid dynamics in general, and how well can you use scientific flow calculation software. The struggle is real and Mentor Graphics has created a solution to ease the process. FloEFD is fully CAD integrated fluid dynamics software and its main purpose is to deploy fluid dynamics calculation for - not only to the flow specialists – but to a general design engineer. It is quick to learn and easy to use because of its clear user interface.

Why FloEFD?

Save costs and time with FloEFD

FloEFD can solve a great deal of flow cases. Everything is covered from heat distribution to combustion processes. You can identify a fluid flow problem by doing a simple flow case around your product with low mesh resolution, improve geometry accordingly, regenerate mesh and rerun the case. There is no need to transfer geometry between software, updated and correct geometry is used in FloEFD at all times. If flow issues with the product continue to occur, at least the issue has been detected and general design engineer can point it out to a flow specialist, who can then use FloEFD to solve the problem.

Business values

Bring flow simulation closer to the design engineer. More people can investigate flow related issues, therefore problems are detected earlier and costly last minute changes can be avoided. This reduces the amount of rework and projects progress smoother. Prototyping is less expensive because issues are detected before prototyping phase.

How-To

FloEFD connects to Creo Parametric and after you open the model to be investigated, you are ready to go. To simplify the process and ease the geometry, it is recommended to remove the geometry that have nothing to do with the flow case. These can be rounds, bolts, nuts, chamfers or other small geometry.

After preprocessing work, you can start by creating flow project, select all the features and flow phenomena that you want to include in your simulation, select the medium, default solid etc. When the project is ready, you assign flow conditions to the geometry and setup the mesh quality. To set the finish criteria you can set some goals, such as temperature and/or pressure at a point of interest and then run the simulation. Simulation is intelligent and finishes when the selected are not changing any more.

Open results and see cut plots, flow trajectories, surface plots or plots along selected trajectories etc. FloEFD gives the results in a form that you want them to be.
