Discovering the power of Oofelie Multiphysics

DISCOVERY OF Oofelie V2.6,

an industrial multiphysics solution fully integrated in Samcef Field , the gui also used by all Samcef solutions.


About Open-Engineering and Oofelie®

Oofelie®  , the “multiphysics” solver dedicated to multiphysics
CAE, was born in 1991 in the LTAS ( L T A S), 
in Belgium. After ten years of developments under the leads of, Igor
Klapka, Alberto Cardona, and Michel Geradin , Oofelie® began its industrial
life.  Open-Engineering was created by
Igor Klapka , Alberto Cardona and Michel Geradin in association with SAMTECH sa.The core business of
Open-Engineering being to bring Oofelie® Multiphysics to industrial markets,
the developments since then were oriented on “strong couplings” and “openness”.

proposes now a suite of solutions adapted to anyone’s needs at any level. The
flexibility of this offer is a key element in Open-Engineering’s success.

Open Engineering’s offer is made coherent in one
single friendly graphical user interface.

This GUI allows many possibilities and interactions
with other codes like  SAMCEF, MECANO,

 3D CAE – Open-Engineering’s
solution::Oofelie Harmonized Suite


OOfelie Multiphysics incorporates the full range of
OOfelie coupled-fields multiphysics capabilities. It combines structural,
thermal, acoustics, piezoelectric, current conduction, circuits, CFD-Fluids
FEM, mechanical, vibro-acoustics, MEMS and electromagnetic features in one single
design analysis software that performs multiple, high-end analyses and
coupled-field analyses simultaneously, driven by parameterized geometry and
physical data.

It doesn’t  only
uses FEM, but also BEM and FVM, both strongly coupled with FEM, implemented in
a generic way.

Strong and weak coupling are both coupled-field
dynamics analysis methods available in OOfelie Multiphysics.

Monolithic, staggered and sequential resolution
schemes are available in Oofelie, and can be adapted by the user.

Monolithic coupling involves a single design analysis
using coupled-field elements that have multiple degrees of freedom at each
node/edge/face to allow continual cross-coupling between the analytical
disciplines. It is possible to determine complex acoustics/structural response
or piezoelectric phenomena, aero-thermo-mechanics,
pyro-piezo-magnetic-mechanics and articulated flexible mechanisms.

The number of fields is not limited in Oofelie, like
for example with VibroPiezoThermoMechanics monolithic elements.

Monolithic resolution schemes allow accurate and
efficient dynamic simulation, also more suitable for non-linear problems.

They can be used to accelerate Newton implicit non
linear resolution schemes, to keep frequency spectrum consistency of the whole
model, to get sensibility analysis, buckling, pre-stressed modal and harmonic
analysis, to accelerate topological optimization or to create parameterized
super elements.

Staggered coupling involves sequential design
analyses, and can still be accurately used to reduce time integration when some
field has different characteristic time or for static analysis.

The two fields are coupled by applying results from
the first design analysis as loads for the second design analysis and then the
results are re-injected in the first as loads …. the loop goes on as long as
convergence is reached. Weak coupling is also attractive for rapid dynamic
coupled-field interactions with small time step and explicit resolution

Each method proves beneficial to different problems.


Open-Engineering’s Industrial solutions

OOfelie Multiphysics includes also a
self-contained electromagnetic analysis package : OOfelie /Emag, electrostatic
contribution FEM and/or BEM, and a Vibro-acoustics module : FEM-BEM. It does
include also a computational fluid dynamics : CFD-FFSI (Fluid Flexible
Structure Interaction) module : OOfelie Fluid FEM, building implicit resolution
schemes, super-element and reduction methods which can be, for example, used in
MEMS design to obtain equivalent self consistent VeriLog/VHDL-A model of a
microfluidic device.OOfelie  has drivers to interact with Fine Hexa from
Numeca Intl (CFD-FVM), this solution has the capability of solving a variety of
fluid flow problems, including laminar, turbulent, compressible, and
incompressible flow; subsonic, transonic, and supersonic; single or multiple
fluids .It provides multiphysics capabilities, enabling analysis of the
interaction fluid, thermal, and structural phenomena.


A driver for Memspro from Softmems allows you to
combine the layout of circuits and the multiphysics analysis for MEMS

A driver for Zemax will allow you to solve
interactions on Optic-Thermal-Mechanics problems.

Single processor, shared memory and/or distributed
memory parallel algorithms versions are available.


Open-Engineering’s Oofelie
based SDK

By the way, as some engineers may need more, so they can
use the CLI (Command Line Interpreter) that can allow them to introduce not
only data but also resolution schemes and methods adapted to the problem they
want to solve.

For R&D labs, Universities or developers,
Open-Engineering offers a SDK library implementation that enables the full
linking for integration in specific applications. These applications can also
be interfaced in the GUI for any industrial use.

Open-Engineering’s markets.

Open-Engineering has targeted most of the Industries
and R&D labs but didn’t forget academies as well.

The polyvalence of the offer is so flexible that
everyone will find an answer to his needs.

Open-Engineering has set very attractive offers to encourage
 exchanges  between Industies, R&D Labs and Academies.

Open-Engineering is also very active in research &
development with Spatial agencies, big companies for in-house developments on
energy, automotive, robotics … dom

Hi oofelie, I'm reseracher, don't know about your solution.

How to get it and test it?

Do you have any demo license or academic licenses?


Just visit our , follow the link  : ask free demo cd


academic licenses do exist, classroomkits also, sdk if needed and finally licenses for industry.

just ask !




I've been checking on your website, I see that you have a full solution under the same interface, do you have any comparison table between you and ansys?

More further , do you have support and training courses available?



For the story: Oofelie has been developed in one single C++ monoltihic and object oriented code.

This way was chosen to optimize the strong couplings.

We can answer to most of the demands and also more than ANSYS, but we have no industrial solution for High Frequency.

We also import geometries in Step Iges etc... We can use enven the integrated post treatment or others like ParaView.

The structure allows also other codes to dial with Oofelie Kernel.

Regarding Trainings , we have video tutorials, Chinese, english and Portuguese.

We have pdf with contents of training courses.

We also organize trainings here in belgium.

If you need more, don't hesitate to contact

Hi, do you need infos?


Most of users are interested in more popular softwares may be because there is more information about them in the web. also chance of finding person who know that softwares is more.  i suggest you to make a comparision table between your software and similar softwares to show you advantages and also disadvantages of this software. what is possible with your software which is not possible with other more popular softwares?

Thank you I appreciate your suggestion.

I've got an excel table showing clearly the comparison, i can transmit it to everyone who wants to.

In another way I can send demo cd's and also free them for 3 months for free so people can try and discover.
