FloEFD

from Wikipedia, the free encyclopedia
Flow simulation of a muffler, speed distribution represented by streamlines

FloEFD is a software for the simulation of flows and thermal processes, which is based on the finite volume method .

description

Cartesian network (2D representation) for the simulation of a three-dimensional flow around

In contrast to many other CFD programs ('Computational Fluid Dynamics'), Cartesian networks are used in FloEFD . Another important differentiator to many other CFD programs is the use of the Immersed Boundary method . A conventional CFD solver distinguishes between the space through which the fluid flows and solids in that both regions are networked separately and a cell is either fluid or solid. With the Immersed Boundary method implemented in FloEFD, however, a cell can consist of fluid, solid or both. In the simplest case, a Cartesian cell within the solid-fluid boundary consists of two control volumes (KV): a fluid-KV and a solid-KV. By using so-called SmartCells TM , a cell can consist of up to 20 control volumes . FloEFD automatically recognizes resulting flow spaces based on the CAD data and takes these into account when creating the calculation models. This results in time savings when generating the network, in particular when simulating geometrically complex electronic systems. FloEFD is integrated into various CAD systems . The listed properties facilitate the modeling and especially the usually very complex networking process considerably.

FloEFD has user interfaces in German, English, French, Russian, Japanese, Chinese and Korean.

history

The first version of the software was developed at the Moscow Institute of Physics and Technology ( MIPT ) in the 1980s and was known as Aeroshape-3D. In 1998 Nika GmbH from Germany took over the rights to the software and introduced the term EFD ('Engineering Fluid Dynamics'). This should underline that the primary target group are engineers or designers. Solid Works was the first CAD system in which this software was available under the name Flow Simulation. In 2006, Nika was taken over by the English Flomerics Ltd, which in turn was bought by Mentor Graphics in 2008. Finally, Siemens took over Mentor Graphics in early 2017 .
