Computational Engineering Analysis

The Computational Engineering Analysis Group, part of the Nokia Global Products Compliance Laboratory, offers engineering consulting services for product development, research, and testing organizations. The services include engineering using an integrated numerical approach incorporating computational physics modeling (Finite Element or Finite Volume) techniques and Design-of-Experiments (DOE) methodologies. This "virtual" robust product design approach is used to assess product performance, functionality, and reliability through the simulation and predication of design margins.

Analysis of product performance can be conducted for physical systems exhibiting:
  • Linear or non-linear behavior.
  • Solid/fluid mechanics (structural, fluid statics).
  • Solid fluid dynamics (structural impact, fluid flow).
  • Thermodynamics (thermal - heat transfer).
  • Acoustics
  • Electromagnetics (low and high frequency).
  • Couple interaction of these phenomena.

Computation tools for analysis and simulation include:
  • ANSYS Multiphysics (General purpose computational physics).
  • LS-DYNA 3D (Non-linear dynamics, high-speed impact, large deformation).
  • CFX/Fluent (General purpose Computational Fluid Dynamics (CFD).
  • FLOTHERM & ANSYS lcepak (Special purpose, Thermal Management of Electronic Equipment, CFD).
  • Echip (Statistical Experiment Design (DOE))

The following numerical methodologies are used for product analysis and simulation:
  • Parametric Modeling, using variables to represent critical geometric dimensions and/or properties, for efficient exploration of the product's performance envelope.
  • Integrated Computational Physics and DOE for design optimization using Response Surface Methods.
