Modelling of Eddy Current inspections with CIVA
In the aim of fulfilling efficient ECT simulation tools within the CIVA simulation software platform, the CEA LIST has adopted several years ago a semi-analytical modelling approach. Initially limited to the simplest configurations, this approach, based on the calculation and utilization of the Green dyads, is enriched over the years with new models which, once being implemented in CIVA, allow to deal with new and more complex configurations. In this communication, after having briefly recalled theoretical aspects of the modelling approach (Volume Integral Method) we will concentrate on such recent advances. In particular examples concerning new capabilities for tubes inspection (including RFEC configurations) and multi-layered structures will be given. These examples will illustrate the simulation ability to deal with various types of probes (multi-coils, with and without ferrite, etc). For the different cases of applications, the validity of the simulations will be evaluated by comparison with measurements.
