OOFELIE::Multiphysics - Engineering Standard Multiphysics Solutions / Products / The OOFELIE::Multiphysics Suite / Overview

Overview

Strongly coupled multiphysics propels your design into the future.

Successful technical innovation can only be based on robust accurate design. Today’s PLM (Product Lifecycle Management) benefits from using advanced multi-core, multi-grid computer technology. It is now possible to simulate complex strongly coupled multiphysics problems in a single simulation run and thus obtain results that were previously only achievable after lengthy (and time consuming) measurements. As a consequence, accurate multiphysics CAE cuts the number of design cycles and accelerates your innovation capacity.

Why Today’s Sensors and Actuators need Strongly Coupled Multiphysics Design. [top]

Today’s sensors and actuators often involve multiple physical phenomena such as Capacitive –Electrostatics, Piezoresistivity, Piezoelectrity, Accoustics, Thermics, Peltier effects and ElectroMagnetics.
As components are increasingly scaled down (nanotechnology, MEMS), specific microscopicphysical phenomena assume greater importance (Electrostatic effects, Peltier). Furthermore the time constants of these physical phenomena have similar orders of magnitude (electrical, mechanicaland thermal effects). Classical design techniques performing sequentially coupled simulations of the different physical phenomena will yield poor accuracy. Not so with OOFELIE::Multiphysics, which can solve more than 4 of such phenomena in a single, strongly coupled simulation setup for optimal accuracy and convergence.

You can solve microsystem FSI problems such as flow sensors or micro-pumps using OOFELIE::Multiphyiscs.

For large scale problems with complex flow regimes, FINETM/FSI-OOFELIE is an integrated solution for strongly coupled fluid-structure interaction simulations. It combines the latest technology in Multiphysics andComputational Fluid Dynamics (CFD) design.

FINE™/FSI-OOFELIE applications are of crucial importance in critical fields, often those with high security and reliability risks: potentially dangerous fluid-structure interactions (FSI) can occur in aircrafts, such as nozzlevibration, wing flutter or buffeting – and in wind turbine applications. Other Fluid-Structure Interaction applications include fuel tank sloshing or the design of piezoelectric based MEMS for flow characterization.With FINE™/FSI-OOFELIE you do not need to learn, validate and match three different types of simulation software: structure simulation, CFD simulation and MPCCI for data transfer. Instead you can just setup and launch the complete simulation using the integrated FINE™/FSI-OOFELIE solution so making significant savings in setup time as well as improving reliability.

Advanced Optics Design. [top]

Ever more high precision applications are required to perform in demanding conditions. This must inevitably raise the design standards of optical devices with regard to high dimensional stability, increased accuracy and predictable performance. OOFELIE::Multiphysics performs a coupled analysis of Opto-thermo-electro-mechanic interactions linked to Zemax®, including novel optics steering mechanisms such as those based on piezo-electrics and thermo mechanics.

Reduced models (SEM) Solutions for System and MEMS Design. [top]

Reduced Order - or Super Element- Models are used when you need to combine the accuracy of Strongly Coupled 3D multiphyiscs problems with the simplicity of System and Circuit simulation oreven Microsoft Excel™.

Reduced order model for an electromagnetic actuator. A parameterized electromagnetic and structure model of the actuator is processed to characterize the structural, electro-magnetic and coupling behaviors of the device. The result is a reduced order model that returns the force and displacement exercised by the actuator as a function of the electric current applied to the pins.

Super Element Models are used intensively in the microsystems (MEMS) design flow. Simulations at circuit level require accurate compact models of the MEMS components, that are generated from computationally expensive 3D numerical models. The models are generated using HDL(Hardware Definition Language) and inserted, in a circuit simulator for MEMS - Circuit co-simulation such as T-Spice.

The MEMSPro™ design flow links EDA tools layout to OOFELIE::Multiphysics using design kit information from the MEMS manufacturer. The result is a full 3D Multiphysics simulation of the device, that can be exported as a reduced order model for circuit or system simulation.

Speed Up Your Innovation Cycle Using The OOFELIE SoftwareDevelopment Kit. [top]

OOFELIE::SDK lets you implement your new ideas inside an industrial class solution. You will speed up your innovation cycle by building your solution upon an established multiphysics simulation tool.

You can create innovative solutions:

  • Customize OOFELIE. Extend the OOFELIE capabilities using the C++ like scripting functionality or use the SDK to better meet your needs by taking advantage of the toolkit’s APIs.
  • Embed OOFELIE inside your own application. Integrate OOFELIE components inside an existing application.
  • (Re)engineering. Create a completely different application or reconstruct an existing in-house numerical simulation solution with modern components.
  • Compiled models. Create compiled models, directly in C++ using OOFELIE components.
