Abstract
The field of non-destructive testing is a large consumer of numerical simulations, which can be very expensive. Precision constraints can therefore be lowered for the simulation to be achievable on a personal computer, and in an acceptable time. But, this can lead to unacceptable inaccuracies on the result. For this, the \textit{a posteriori} theory offers different estimators studied during this internship, which, at the cost of a more expensive calculation, allow to follow the precision of a simulation during its realization. They allow to validate or invalidate its results in real time. This work describes the analysis and implementation of such estimators in an industrial simulation software framework.
