In the context of ultrasonic NDT, modeling can help data interpretation by comparison of measured and calculated results. It is also useful to optimize testing configurations more easily and at lower cost than experimental studies. Moreover it may constitute an efficient tool for professional training of NDT experts. For all these reasons the CEA/CEREM has developed for several years user-friendly modeling tools especially adapted to industrial applications and leading to accurate quantitative predictions in short computation times. To fulfill these requirements approximated models have been derived to treat radiation, propagation, and echo formation on defects and boundaries. This paper aims at presenting the resulting softwares which are implemented in the NDT data acquisition and processing system CIVA. This implementation allows one to directly compare measured and computed results by taking advantage of imaging and processing tools included in CIVA.
