With our highly efficient solvers, full 3D models can be simulated in short time frames to allow your full design to be evaluated without assumptions and simplifications. Here is a quick example of 3D transducer stimulated with a pulse and ringing down in an open air environment.

Low Frequency Sonar

Housing resonances can significantly affect device performance, in particular at frequencies below 20 kHz where wideband hydrophones and parametric arrays can operate. Resonances can be difficult to predict and may only be detected late in the design cycle. With PZFlex’s highly efficient electro-mechanical solver, ability to generate multi-million element models and wideband results from a single run, it allows complex …

Matching Layer Optimisation

Designers often prefer to run multiple simulations to explore the best solution within a design space in order to meet client specifications. PZFlex is very well suited to carrying out such design studies given its ability to deliver high performance designs in short timescales. In combination with our PZFlex Cloud service, models can be simulated in batches or in parallel …

Transducer Heating

Subjecting transducers to high input powers can generate significant temperature rises within the device. The resultant temperature depends on the thermal properties of the materials used, efficiency of the transducer and the operating environment. PZFlex separates the design problem into an acoustic simulation to calculate losses which can be input into a thermal model to solve for the temperature gradients. …

Stacked Horn Transducer

Typical PZFlex models are generated on standard partition mesh which is why the code is very quick to run. However we can also model using general connectivity and skewed elements for more complex geometries. The stacked horn example uses a skewed grid to accurately represent the curved tip features. The horn was modeled with: 6 discs of PZT4D connected electrically …
