The use of the COMSOL Multiphysics software package for modeling ultrasonic inspection, which is an important method of non-destructive testing in many industries, is investigated. The capabilities of COMSOL Multiphysics in comparison with other common ultrasonic inspection simulation programs, such as Ansys, MATLAB, Abaqus, and PZFlex are considered. The advantages of COMSOL Multiphysics are analyzed, in particular, its ability to model multiphysics processes, user-friendly graphical interface, and extensive integration with other software tools. Attention is paid to how COMSOL Multiphysics allows to take into account the interaction of various physical phenomena, which is critical for accurate modeling of ultrasonic inspection, where it is necessary to analyze the complex interaction of ultrasonic waves with the material under study and the defects present in it. COMSOL Multiphysics provides a wide range of tools and modules that allow you to model various aspects of ultrasonic inspection. This article describes in detail the COMSOL Multiphysics modules and tools used for acoustic wave modeling, including the Acoustics Module, Structural Mechanics Module, and Multiphysics Coupling, are described in detail. The possibility of modeling various types of ultrasonic waves using COMSOL, including longitudinal, transverse, and surface waves, is considered. The results of modeling ultrasonic control using COMSOL Multiphysics are presented. The processes of wave propagation, pressure distribution, distribution of electric potential in the transducer, and distribution of mechanical stresses in the test sample are visualized. The influence of the presence of defects in the material on the characteristics of ultrasonic inspection signals is analyzed. The obtained simulation data allow us to clearly demonstrate the capabilities of COMSOL Multiphysics for visualization and analysis of ultrasonic inspection. It is confirmed that COMSOL Multiphysics is a powerful tool for the research and development of non-destructive testing methods, including ultrasonic testing. Directions for further research using COMSOL Multiphysics in the field of ultrasonic inspection aimed at developing new diagnostic methods and optimizing existing ones are proposed.
