In our previous blog post, How to Assign Mechanical and Electrical BCs to Array Structures we showed you how to apply boundary conditions (BCs), calculate arrays, request outputs from the solver, calculate timestep by calling PRCS and set up the execution.

In a recent blog post, How to Build Arrays in OnScale we discussed how to build and control the size of the array structures using parameters. In this post we will look at how to assign mechanical and electrical boundary conditions (BCs) to this model and set up an execution loop to run the model on the cloud.

Ultrasonic phased array testing is a powerful non-destructive testing (NDT) technology which is growing rapidly.

When I joined OnScale I had just graduated from university. I’ve got to admit, straight out of university a lot about the world of Computer Aided Engineering (CAE) and Finite Element Analysis (FEA) was still a mystery to me. FEA is a fascinating area -- but I think it’s fair to say that it can at times seem daunting to beginners!

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.

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.

Introduction Understanding the complex, highly coupled behavior of electromechanical sensors and their performance within a system is critical. OnScale allows users to simulate device behavior, quickly assess design changes and ultimately optimize the designs. OnScale is working with leading oil and gas companies to optimize their ultrasonic sensors and measurements systems. A range of applications from basic sensor design, to downhole imaging and flow measurements will be presented in this article.
