Ultrasonic NDT Simulator with engine core based on the Elastodynamic Finite Integration Technique (EFIT) (P/SV: 2th spatial-time order) for Elastic/Viscoelastic media to model the wave propagation in 2D for viscoelastic and elastic materials [1].

The SimNDT has a very friendly and easy to use GUI. This software is able to simulate different ultrasonic inspection methods as Pulse-echo, Through-Transmission, Linear Scan, as well as Scan and Tomography. In addition, it is capable to generate or import different types of geometric scenarios and export simulation results in mat-file format for further processing.

To improve the performance of this technique the software was implemented using the standard for parallel programming of heterogeneous systems, OpenCL (Open Computing Language). It works in both multicore processors and GPU's (Intel, NVIDIA or AMD)

Please before using it and depending of your system, install your required OpenCL Drivers:
