The OOFELIE::Multiphysics Suite

BannerOOFELIEMultiphysicsSuite

The OOFELIE::Multiphysics Suite provides you with unique capabilities to analyze industrial applications such as:

  • Sensors and actuators, including MEMS (Micro-Electro-Mechanical Systems)
  • Optomechanical systems including MOEMS (Micro-Opto-Electro-Mechanical Systems
  • Multidisciplinary systems where an interaction exists between a fluid medium and a structure (F.S.I. - Fluid Structure Interaction)

The OOFELIE::Multiphysics Suite is composed of three major components:

  1. OOFELIE::UI, the parametric graphical user interface
  2. OOFELIE::Multiphysics Solver, the multiple field solver to predict the behaviour of your application
  3. OOFELIE::ADX, the solution to explore the design space and optimize your model
OMP_Suite

The OOFELIE::Multiphysics Solver is integrated in an engineering standard, intuitive user interface providing time-saving design flow including scripting parameterization and optimization. Fully and strongly coupled FEM/BEM/FMM simulations between relevant physical phenomena yield fast convergence and efficient handling of supersized problems.

The OOFELIE::Multiphysics Solver combines thermics, mechanics, acoustics, electrics fields and couplings (electrostatics, piezoresitive, vibro-acoustics, piezoelectric, peltier, circuits, FEM fluids, Optics links, MEMS and electromagnetic features in one single CAE environment.

3D CAE

The OOFELIE::Multiphysics Solver does not only make use of the Finiet Elements Method (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 schemes. Each method proves beneficial to different problems.

Industrial solution

OOFELIE::Multiphysics includes also a self-contained electromagnetic analysis package: electromagnetics, 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/Open 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 simulation.

A driver for OpticStudio will allow you to solve interactions on Optic-Thermal-Mechanics problems. Single processor, shared memory and/or distributed memory parallel algorithms versions are available.
