Optimizing guided wave (GW) examinations or interpreting GW measurements can be greatly helped by simulation tools dealing with complex propagation and scattering phenomena. Tools are developed exploiting the modal nature of GW, this simplifying interpretation (no postprocessing as required when results are computed without reference to modes). Two modal formulations simulate measurements (pitch‐catch, pulse‐echo); they link a semi‐analytic finite element code for computing modes, models for transducer diffraction and a specific finite element model for scattering by arbitrary discontinuities. The paper reviews these tools; examples illustrate their interest.
