Product Description

PZFlex Software


It pushes the limits of Finite Element Analysis on a desktop PC.

PZFlex® is one of the fastest and most accurate finite element (FE) software packages commercially available. It can solve multi-million element models on a PC in a few hours, not the days or weeks of other programs. Comparable off-the-shelf programs for simulating complex devices and their load environments lack its pedigree and achievements in a variety of industrial settings. Developed in the 1980s to improve the modeling of ultrasonic probes, PZFlex quickly became the most versatile member of a family of codes (Flex) that are used to solve huge wave-propagation problems for the US government. During the past two decades of intensive development, PZFlex has spawned numerous applications and attracted increasing numbers of clients.

WHO is behind PZFlex?

Engineers who speak your language.

PZFlex is a commercial product with a difference: it is designed and supported by engineers who have advanced degrees in acoustics along with research interests of their own. You benefit from their need for cutting-edge quality software, as well as their more than 30 years of computer modeling experience. When you communicate with them, you are pleased to discover that they understand not only the modeling problem, but also the physical problem you are trying to solve.

WHERE is PZFlex used?

In corporations and research institutions all over the world.

Experts in fields as varied as MEMS, sensors and actuators, NDT, and telecommunications use PZFlex It is an extremely adaptable program that models and analyzes piezoelectric materials, acoustic fluids, isotropic and anisotropic solids, electrostrictive and magnetostrictive media, as well as nonlinear tissues and electrostatic environments. It is first in world markets for medical therapeutics and sonar and the program of choice for all major U.S. and Japanese medical transducer manufacturers. It also supports important studies and investigations in diagnostic and therapeutic medical ultrasound at prominent academic institutions. Continuing research sponsored by the Defense Advanced Research Projects Agency (DARPA), the Office of Naval Research (ONR), the National Science Foundation (NSF), and the National Institutes of Health (NIH) ensures the software’s development.

WHEN is PZFlex the obvious choice?

During any phase of a project, from concept through production.

Researchers, inventors, and manufacturers choose PZFlex over its competitors whenever they have to analyze an ultrasound or piezoelectric device quickly and accurately. The virtual prototypes produced by PZFlex shrink the number and duration of time-to-market design cycles by reducing the number of expensive physical prototypes required. It is the only alternative when customer demand for lower costs is coupled with competing demands for higher frequencies and greater sensitivities and bandwidth. Moreover, PZFlex models put your device in context, expanding it to include the load environment and to support academic “what if” studies. The models can be used to point up inconsistencies in the manufacturing process or materials and to detect “sweet spots,” trends, and unexpected behaviors.

WHAT does PZFlex do differently?

It gives real-world solutions to real-world problems.

PZFlex is more efficient than other programs because it takes a finite-element and explicit time-domain approach to solving large, complex 1D, 2D, and 3D wave-propagation problems. All of its features have one common goal: to deliver valuable real-world results in an accelerated timeframe.

  • Its fast and efficient algorithms produce accurate models of a size and scope that is out of reach for comparable FEM products. This supports modeling of significantly larger device components and entire devices and their housing to better understand the device’s performance.
  • Its solvers can fully analyze solid and fluid elements and electromechanical coupling effects in piezoelectrics.
  • Its tested post-processing tools make for simple generation of electrical impedance spectra, beam profiles, and TVRs, allowing you to compare output to experimental results directly.
  • Its comprehensive range of element types allows you to analyze a comprehensive range of media, from acoustic fluids to nonlinear tissues.
  • Its advanced capabilities, beyond those of 1D models and common “rules-of-thumb,” include complex modes in nondestructive testing arrays, electrical crosstalk between the fine electrodes on biomedical devices, and interactions of towbodies with the sonars they contain.
  • Its add-on packages support nonlinear electrostatic analyses and long-distance wave propagation (the behavior of nonlinear materials is represented by a traditional “B/A” model).
  • A full set of thermal solvers calculates temperature and thermal-mechanical effects.
