Strong Multiphysics Coupling

Tue, 26 Jan 2010 15:52:26 GMT

Strong coupling of multipysics phenomena reveals much more information than just consecutive simulations. As an example, the coupling factors can simulate the mutual influence of a wing deformation on the airflow around it. Simulations can combine thermo mechanical stresses inside a structure with pressure and temperature exchange from a surrounding flow.

It ensures fast convergence and solution stability simulating multi-unstable invironments.

Super Element Models (SEM) generation

Tue, 26 Jan 2010 11:28:18 GMT

Thanks to the strong coupling approach, model reduction techniques are available to generate accurate but fast models of components that can be introduced in other electronics.
Efficient and innovative reduction methods have been developed in Oofelie, which allow the generation of parameterised multiphysics reduced models that are fully compatible with static, modal, dynamic and harmonic simulations. The use of reduced models can lead to significant improvements in terms of simulation time and memory requirements. Furthermore, the ability to re-use components and to generate models that represent families of components, thanks to the parameterisation features, can speed-up the time-to-market.
The reduction methods available in Oofelie can be applied to structural, thermo-mechanical, piezoelectric and thermo-piezoelectric models.
Due to the dynamic reduction approach, reduced models take into account the complete behavior of the models, including stiffness, inertial and damping effects. In addition, all the reduced model variables correspond to input-output quantities and therefore the excitation scheme must not be defined a priori when generating the reduced model.
Reduced models can also be exported to systems simulators using VHDL-AMS or Verilog-A exchange formats. It is also possible to add and connect multiple RLC circuit elements to model the connected circuitry directly inside Oofelie::Mems.

Fluid damping

Tue, 26 Jan 2010 11:27:30 GMT

For MEMS devices that are not packaged in a vacuum environment, the management of the surrounding fluid medium is mandatory. Indeed, it induces an additional damping effect that modifies the dynamic behaviour of the system. A BEM Stokes fluid incompressible formulation is implemented in Oofelie::MEMS to model this damping effect.

Thermo-mechanical and pyro couplings

The Oofelie::MEMS product contains all the capabilities of the Oofelie::PyroPiezoElectric product, where the thermal field and its couplings with mechanical and electrical fields are taken into account in the strongly coupled analysis procedures.

Electrostatic actuation

Tue, 26 Jan 2010 11:24:43 GMT

The electrostatic capabilities are dedicated to the modeling of the behavior of electrostatically actuated systems. This feature is very flexible thanks to the use of the conventional finite element method (FEM), together with the boundary element method (BEM). This last method is efficient for taking into account the contribution of infinite medium. Also, a Fast Multipole Method (FMM) algorithm can be used, in some specific cases, to solve very large electrostatic problems with BEM techniques.

Piezoelectric analysis

Tue, 26 Jan 2010 11:24:11 GMT

The general three-dimensional models offer generalized methods that can be adapted and used for many different applications in the transportation (aircraft, automotive), equipment (machinery, motors, sound systems), electronic appliances, biomedical and building industries for instance.

To accurately model the behavior of piezoelectric systems, the strong coupling between the mechanical and electrical fields is considered in the solution approach.

Strong Coupled Fluid Structure Interaction Specifications: FINE/Oofelie FSI

Wed, 20 Jan 2010 07:52:38 GMT

FINE/Oofelie FSI is a fully integrated solution for strongly coupled fluid-structure interaction simulations. It is developed by Open Engineering and Numeca International , combining the latest technology in Multiphysics, Computational Fluid Dynamics and Mechanics design.

FINE/Oofelie FSI applications are very important in critical fields, with often high security and reilability risks: Potentially dangerous fluid-structure interactions (FSI) can occur in aircrafts – e.g. wing flutter or buffeting – and wind turbines applications. Other Fluid-Structure Interaction applications are fuel tank sloshing, drop testing of liquid filled containers, detonation wave effects on structures, pressure vessel analysis, fluid interaction with valves and elbows, explosively formed projectile (EFP) analysis, airbag deployment, parachute development, injection molding analysis, wind-force analysis on tall buildings and earthquake response of liquid storage tanks (nuclear waste disposal),

Mesh for a plane wave diffraction by a submarine (length : 37 meters) excitation frequency : 1500 Hz (< 2GB RAM, 44mins)

The acoustic media can be modeled using Finite Element Methods (FEM) or Boundary Element Methods (BEM). The coupling of both is an ideal approach when complex surfaces radiate into a large space.On top the Fast Multipole Method is used to simulate acoustic radiation/diffraction problems with large number of degrees of freedom using BEM methodology. This approach enables you to reduce memory by a factor 20, and speed up simulations by a factor 50.
