A Fast Ultrasonic Simulation Tool based on Massively Parallel Implementations

Abstract : This paper presents a CIVA optimized ultrasonic inspection simulation tool, which takes benefit of the power of massively parallel architectures : graphical processing units (GPU) and multi-core general purpose processors (GPP). This tool is based on the classical approach used in CIVA : the interaction model is based on Kirchoff, and the ultrasonic field around the defect is computed by the pencil method. The model has been adapted and parallelized for both architectures. At this stage, the configurations addressed by the tool are : multi and mono-element probes, planar specimens made of simple isotropic materials, planar rectangular defects or side drilled holes of small diameter. Validations on the model accuracy and performances measurements are presented.
