Multiphysics for designers / About Us / History

History of the company

Accurate and efficient strong coupling is our core business. Coupling FEM, X-FEM, BEM, FVM, DEM expertises with OOP and Numerical Computer Science, Open Engineering offers taylor made dedicated products or services to solve your design problems. 15 years know-how in Object Oriented Methodologies led us to practice Uml, Re factoring and Agile's methods every day.

Open Engineering designs, develops and sells a multi-physics software toolkit named OOFELIE::Multiphysics® for modeling and design of electro, thermal, optical and mechanical systems, integrating electrostatic effects, acoustics, phase change and fluids.

Open Engineering also provides project and product design services, and participates in joint industry and academia R&D partnerships for the next generation of sensors and actuators, including micro technologies constraints. Multi-physics simulation capabilities including fluids, heat transfer, stress/deformation, acoustics, electrostatics, and other disciplines make our integrated platform powerful to design complex devices and complete systems. Oofelie framework is a design flow software tool for rapid virtual prototyping, parametric simulations, and design optimization for electromechanical systems. It automatically generates meshes from parametric geometries, solves complete multi-physics problems, and provides customized parametric designs.


Industry needs a unified analysis tool coarsely integrated in one design flow to reduce design costs.

Research centers and Universities do not want to spend more time in re-inventing the wheel and need unified collaborative platform.

The proposed approach to reach these requirements is, starting from Oofelie multiphysics platform (CSL shared with research centers), to Open Multidisciplinary.

The OOFELIE::Multiphysics project started inside the Structural Dynamic Group of the LTAS (Laboratoire des Techniques Aéronautiques et Spatiales) of Professor Géradin by the cooperation between Igor Klapka and Alberto Cardona from INTEC (Argentina).


Two leading ideas :

"Are object oriented methodologies the future way of accuracy and sustain development for scientific numerical computation? What about C++ or FORTRAN? "

"Is it possible to unify disciplines and their methods inside a single framework in order to be well prepared to answer tomorrow challenges : multidisciplinary analysis and virtual prototyping?"

Researches were performed in this sense, based on object oriented philosophy and the use of associated methodologies (OOD, G. Booch, OMT, UML) applied to numerical computation without deteriorate performances obtained with the structured FORTRAN language.

These researches have conduct to three advantages for the object oriented languages:

  • Better robustness of the code and guarantee on the reliability of the implementation of algorithms
  • Reduction of efforts of maintenance and extensibility of the code generated
  • Better capability to become integrated into present tools and graphical interfaces.

Open Engineering is a spin-off from the University of Liège created in December 2001 to capitalize on the OOFELIE::MultiphysicsToolkit.

Using OOFELIE::Multiphysics, its open multidisciplinary toolkit, Open Engineering wants to develop its missions on four main activity fields:

  1. Industrialize and enhance OOFELIE.

    The goal is to integrate multiple disciplines inside a unique simulation framework. This allows to optimize the functioning of complex systems, possibly under strong multi-physic constrains (mechanical, thermal, acoustic, electromagnetic, fluid, ...). Oofelie brings functional gateways allowing the construction of multi-physic software's from generic validated components.

  2. To integrate and to enrich current proprietary software thanks to OOFELIE components.

    Indeed, OOFELIE allows to facilitate the migration of such software to new architecture to allow them to easily evolve in terms of functionalityies and maintaining and/or to add a multi-physic dimension.

  3. To place an unifying and shared development framework at educational university laboratories, public and private research laboratories' disposal.

    Components of the OOFELIE toolkit allow, in a more efficient way than with standard tools, to conceive numerical models of multi-physic phenomenon using the finite element and boundary element methods.

  4. To advise industries using his know-how of software engineering applied to multidisciplinary mechanical engineering.

Open Engineering thus proposes:

  • To produce Taylor-made software customize to the client
  • To adapt resolution methods not available inside current software, particularly for multi-physic problems
  • To enrich functionalities of current software
  • To produce integrated tools for design and analysis
  • To propose study services
  • To help the migration of tools written in FORTRAN and/or with Matlab to stand-alone, object oriented and numerically performing software
  • To coordinate customer needs with the help of universities and research centers from its user community.
