Time of Flight Diffraction is a reliable method of non-destructive ultrasonic testing used to look for flaws in welds. In Time of Flight Diffraction (TOFD) systems, a pair of ultrasonic probes reside on opposite sides of a weld-joint or area of interest. A transmitter probe emits an ultrasonic pulse, which is captured by the receiver probe on the opposite side. In an undamaged part, the signals picked up by the receiver probe are from two waves: one that travels along the surface (lateral wave) and one that reflects off the far wall (back-wall reflection). When a discontinuity such as a crack is present, there is a diffraction of the ultrasonic sound wave from the top and bottom tips of the crack. Using the measured time of flight of the pulse, the depth of the crack tips can be calculated automatically by trigonometry. This method is more reliable than traditional radiographic, pulse echo manual UT (Ultrasonic Testing) and automated UT weld testing methods.

“Insufficient RAM”

Join OnScale and Silterra to learn how OnScale has been adopted into their design process of Piezoelectric Micromachined Ultrasonic Transducers (PMUTs). We’ll be showing exciting PMUT results that are obtained in project collaboration with Universitat Autònoma de Barcelona (UAB) with mutual designs, measurements and joint papers and conference publications.

There can't be anything more irritating than getting an error in the middle of your work. However, not knowing why is even worse. We have prepared a few tips and a dedicated Help Center articles to help you tackle these errors and get you back up and running with OnScale.

We had the opportunity to host a joint presentation together with our valued client, Verathon, at AWS Chicago Summit. The AWS Summit is an event designed to bring together the cloud computing community to connect, collaborate, and learn about AWS. Our CEO, Ian Campbell, and Sr. Manager of Research & Systems Engineering, Dr. Kendall Waters, delivered a joint keynote on how OnScale helped Verathon to solve their problems using OnScale cloud-based CAE.

Running thousands of simulations in parallel is natural for us at OnScale. Engineers have full control of their parametric variables, allowing massive design studies to be explored in a very simple, fast manner.
