PZFlex Finite Element Modeling Package

PZFlex is a software package specifically designed for wave propagation, piezoelectric, and ultrasonic applications. Using a finite element-based explicit time domain approach,


PZFlex can solve large, complex 1D, 2D, and 3D wave

propagation problems quickly and efficiently. Because of these efficiencies, PZFlex can model significantly larger device components than most other FEA codes.

A comprehensive range of element types allows analysis of piezoelectric materials, acoustic fluids, isotropic and anisotropic solids, electrostrictive and magnetostrictive capabilities, and non-linear tissues. An add-on package supports non-linear electrostatic analyses. Also included is an extensive suite of analysis and display post-processing tools, built up over many years of close collaboration with

major biomedical, industrial, and naval facilities around the world. Running on a range of hardware platforms including


desktop PCs, PZFlex places a powerful tool in the hands of the engineer and designer, allowing rapid and cost-effective analysis of existing designs, optimization for future systems, and blue-sky research unheard of even a few years ago.

PZFlex Features

  • Full 2D and 3D solvers.
  • Time domain solutions, ideal for broadband results with a single simulation.
  • Isotropic and anisotropic solids and fluids (linear and non- linear).
  • Piezoelectric, electrostrictive (3D), and magnetostrictive (2D) materials.
  • Thermal and thermal-mechanical solvers.
  • Circuits.
  • Extensive post-processing capabilities.
  • Program designed to address very large models (models containing over 10,000,000 elements are well within the ability of the code to simulate on a desktop PC).
  • Sophisticated absorbing boundary condition allows truncation of large continuum domains.
  • Integrated graphics for display of model at any point during analysis.
  • REVIEW postprocessor for display and manipulation of time history data including FFT and impedance computations.
  • Add-on electrostatic solvers available.
  • Add-on long-range acoustic solver.

Explicit Time Domain Approach – Huge Models on your Desktop

Finite element analysis has been used for many years in fields as diverse as civil engineering and aircraft design, and various analysis techniques have been developed to suit  the individual requirements of these applications. Because  PZFlex is used to solve “real world” problems, the output is needed in a “real world” manner; that is, in the time domain.  There are two main methods of time integration: implicit  and explicit


Virtual Prototyping with PZFlex

PZFlex can be used to improve design and to reduce costs and time to market in a straightforward manner, using a procedure called “Virtual Prototyping.” The traditional method of device design involved an initial design based on the experience of the engineer, which was then sent to a workshop for manufacturing. Once completed, this device would then go to an experimental lab, where its performance would be measured. Based on these results, a decision would be made as to whether the device performed acceptably and should go into production, or if a redesign was required. This process would likely take many iterations until completed.
