Nozzle inspection simulation assistant

In CIVA2020, a dedicated environment for nozzle inspection simulation has been introduced. The goal here is to provide some tools to help optimize the inspection of such complex components.  User starts by defining a defective area in the connection zone, and a range of target angles to reach the defect. CIVA will give accessibility maps to investigate where can be positionned a probe for that target. Then,  the user selects a transducer and again a defective zone and target angles for the beam on the defects. CIVA will then compute sensitivity maps to visualize the defect ultrasonic amplitude response as a function of incidence angles or transducer positions, while defining scanning patterns, focal laws and optimal configurations.

FEM calculation

In CIVA2020, an array of models is provided in order to reach the best compromise between accuracy and computation time. This now includes a 2D and 3D FEM model directly included in CIVA UT for crack-like defects modelling, with planar or complex shapes (surface breaking ones with planar or cylindrical back walls, or embedded defects). This is based on a hybrid method using the fast and efficient pencil models to simulate beam propagation connected with a FEM beam/defect calculation in box(es) around defect(s). You can deal with issues such as defect tip sharpness impact, defect sizes below the wavelength, or complex wave modes generated at the defect interaction such as creeping waves. Some random variability can also be introduced in the crack morphology to evaluate its impact on the detection sensitivity. A specific grid editor let’s the user define the defect geometry from which the FE mesh is generated.
