Two modules are sold as add-ons to PZFlex, enhancing its capability for specific types of problems and devices. The PZFlex team can discuss these modules with you in further detail.

CMUTS Module
The CMUTS module is available as an add-on to PZFlex. It expands the range of simulation possibilities for capacitive micromachined ultrasonic transducers and other electrostatic devices. The software matches the original PZFlex piezoelectrics package for accuracy and versatility. It captures the full range of dynamic behavior: transmitting and receiving, biasing, crosstalk, and collapse and collapse/snapback operation contact. It also accounts for the material and geometrical nonlinearities that dominate the operation of these devices.

SPFlex Module
The SPFlex module is a specialized time-domain solver for computing waves that propagate through acoustic media over long distances or that are focused and intense. The software has a wide range of applications in medical diagnostics, therapeutics, and sonar. Its “pseudospectral” formulation eliminates the numerical dispersion common to traditional finite-element and finite-difference formulations, providing results that are highly accurate for thousands of wavelengths. SPFlex may be purchased as a standalone package as well as an add-on to PZFlex.

What is the benefit of purchasing both PZFlex and SPFlex?
There are distinct advantages to buying SPFlex as part of the PZFlex package, rather than as a standalone. For example, the program can be initialized with the pressure field produced by a piezoelectric device that was computed using PZFlex and then used to compute the long-range propagation of this pressure. Using PZFlex and SPFlex together creates a feedback loop between a device and its effects that is helpful to the designer and benefits the design. Additional discounts are available for customers purchasing both PZFlex and SPFlex.
