Medical Diagnostics and Therapeutics

Our familiarity as patients with images of our fetuses and ailing knees are testimony to the power and success of Weidlinger's PZFlex software. It is the preeminent software program for ultrasound modeling and piezoelectric transducer design, in use by commercial companies and academic institutions around the world. PZFlex simulates larger models more quickly than competing products on the market today. All major medical diagnostics companies, including Philips, GE, Siemens, and Hitachi, rely on the PZFlex program to advance the state of the art of piezoelectric transducer design that results in improved ultrasound images. SpectralFlex, another FLEX family tool, is used in the related and growing field of medical therapeutics to model the heat generated in tissues by focused ultrasonic waves for improved drug delivery, increased rates of healing, and destruction of cancerous cells.

Optics

EMFlex has been used for many optics applications, such as improving quality control in the manufacture of integrated circuits and increasing the light-reflecting capacity of paint. It has also been used to design photonics components that support future development of optical computers. The software solves Maxwell’s Equations to compute the propagation of electromagnetic waves through dielectric media.

Counterterrorism

Since September 11th, Weidlinger's blast and impact software, tested over decades, has been used by the firm's engineers to provide timely and accurate support for blast vulnerability assessments, blast-resistant design, and forensic investigations of terrorist attacks. The tools continue to evolve to support the effort of protecting the public, setting priorities based on risk assessment, and expanding design options to include large expanses of glass for atriums and curtain walls. NLFlex is one of the most advanced modeling tools available today for structures subjected to terrorist blast loads. WAI-MAZ, another in-house resource, is used to compute accurate airblast loading pressures for problems that require it. FTS enhances NLFlex's usability with a graphical pre-processor that generates and computes the blast response of structural models in minutes, drastically reducing the time required to perform high-fidelity simulations for design projects.

Structural Failure Assessment

NLFlex is particularly suited to analyzing the complicated behavior of structures that fail. It represents and quantifies a regime of nonlinear behavior that can be ignored under normal conditions but is crucial to establishing causation in the contexts of litigation and remediation. In practice, NLFlex reveals the minute details that often have a disproportionate contributing effect on the mechanisms of failure. It is a tool used with confidence by engineers engaged in this type of detective work, because its validity has been demonstrated in high-profile cases, notably Weidlinger’s investigation of the World Trade Center Towers collapses

Oil Exploration

Several Weidlinger software programs contribute to oil exploration. INTEGRA is a ray-tracing software system that assists geophysicists in developing the accurate images of subterranean geological structures they depend on to locate oil reserves. The paths of seismic waves are traced through its models of Earth's crust, which the software renders in 3-D, increasing the visibility of the structures that lay hidden under the surface. PZFlex has been used to improve the design of piezoelectric sensors for oil-drilling borehole applications and is also the code of choice for computing the full-wave fields generated by seismic sources.

US Department of Defense

Much of Weidlinger's software was developed to support contracts with government agencies, such as the US Army, Navy, Air Force. and Defense Threat Reduction Agency. NLFlex is one of the premier tools for simulating damage to hardened and conventional structures from conventional weapons. WAI-MAZ, a computational fluid dynamics code, is used to provide airblast loading for NLFlex models, to ensure high-fidelity results for complex airblast scenarios. EPSA was developed for modeling complex ship structures and computing their transient response to blast pressures. UNDEX computes blast pressures on naval structures caused by underwater explosions. SRUE computes their effects on surface ships and ELSHOK on submarines. PZFlex is used to simulate and design sonic transducers and the sonar signals generated by them. WASCAT is used to characterize the acoustic signatures generated by mechanical equipment aboard submarines, aiding in the design of quieter ships, which are less likely to be detected by sonar listening devices.
