PZFlex

PZFlex is a commercial software package for finite element analysis and virtual prototyping, developed by Weidlinger Associates Inc, USA. It was an outgrowth of the Flex family of codes developed for structural engineering.

The PZFlex code uses both Explicit and implicit methods.[1] It is a time domain solver that specializes in large wave propagation problems, with emphasis on problems featuring electro-mechanical materials such as piezoelectric ceramics.[2]

The explicit solver is designed to tackle both highly non-linear transient phenomena and quasi-static problems. The package is available for Windows and Linux platforms, both 32 and 64-bit systems. It was developed in the later 1980s to meet the demands of the medical ultrasound imaging device industry[3] and has been adopted for use in the automotive, aerospace, sonar,[4] MEMs and Non-destructive testing[5] industries.

It has also become popular with leading ultrasonic research groups in academia due to its flexibility and speed for solving large, complex problems.

PZFlex stands for PiezoElectric Fast, Large and EXplicit.
