Product presentation
3D CAE
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 Oofleie::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 : 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 : OofelieFluid 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 simulation. 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.
