Traditional high data rate communication realized by electric components – such as A/D converters, encoders, modulators, amplifiers, processors and similar integrated circuits – faces a challenge as further increase of frequency would result in cooling problems due to the generated amount of thermal energy in the form of Joule heating. An alternative approach is light-based information transfer in guided structures, such as optical fibers. However, optical fibers occupy relatively large spaces due to the limited minimum size of bends allowed by the small refractive index difference between the wave guiding core and the outer cladding.
Sonic Logs first appeared in 1957. Sonic logs rely on the properties inherent in Snell’s Law to propagate sound from a logging tool through the rock to receivers located on the same logging tool.
One of the inherent problems with old legacy FEA software is the inability to run large problems – for example legacy simulation packages lack the capability to simulate large arrays in full 3D . This has stunted the development of devices such as PMUTs as the full systems couldn’t be properly simulated.
In this article, we will discuss scripting in OnScale and show you how to build the most basic model in OnScale using only 11 lines of code.
Our Senior Application Engineer, Jeff Dobson will be attending NDT Aerospace 2019. The 3 day event will take place in Paris-Saclay, with over 200 participants expected to attend and over 100 technical presentations. Jeff will be presenting on improving ultrasonic inspection of tapered CFRP structure using cloud based FEA simulation. With the event just over a week away, we thought it would be the perfect time to share with you an interview with Jeff and our Director of Engineering, Cyprien Rusu discussing Non-Destructive Testing.
In this article, we will discuss Genetic Algorithm and how it can be used for Film Bulk Acoustic Resonator (FBAR) design optimization.
With OnScale, full 3D Piezoelectric Micromachined Ultrasonic Transducer (PMUT) array simulations can be carried out. While single cell results are useful, the ideal workflow would go much further. OnScale’s ability to solve large problems allows engineers to move beyond an initial single cell model and help to consider the effect of full array configurations. Using PMUT’s as an example, designers are now using OnScale to simulate PMUT arrays with the full display stack up, allowing them to assess the impact of manufacturing tolerances on imaging arrays.
Last week OnScale were silver sponsors at IEEE IUS 2019 in Glasgow. The event was extremely successful, and we were delighted that so many event attendees were attracted to our booth. We’d like to thank everyone who stopped by booth #14 to speak with us!
