UMASIS, an analysis and visualization tool for developing and optimizing ultrasonic inspection techniques
Simulation tools are more and more used during the development and optimization of ultrasonic inspection techniques. Their advantages are clear. They give additional insight in the performance of an inspection technique at low cost. Furthermore, they overcome practical limitations like availability of transducers and test blocks during the design of new techniques. There are already a number of modeling tools available; most of them use semi-analytical methods to speed up calculation time. They solve approximations of the full elastic wave equation and therefore do not take all wave phenomena into account, like mode conversion and complex reflection. These algorithms also limit the visualization possibilities. UMASIS is a software tool that takes a different approach. It uses the power of wave equation based algorithms to calculate the full elastic wave field. All wave phenomena, like mode conversion, are automatically taken into account. Furthermore, the calculation of the wave field allows advanced visualization possibilities, like decomposition in P- and S-waves. UMASIS communicates over the Internet with a high performance computer cluster which reduces the extensive local computer resources. This way the user can focus on developing and optimizing inspection techniques. This paper further discusses the advantages of simulation tools and the unique approach UMASIS takes. The advantages of UMASIS will be demonstrated on several cases.
