3. Inverse methods and commercial software

We have seen how important modeling is for solving inverse problems: it is indeed necessary to be able to simulate measurements in direct mode first. It has already been pointed out (§ 2.5 of [BE 8 265] ) that different models are generally available to deal with a conduction problem ranging from a 3D phenomenon to a 0D phenomenon: the main idea being to build and use a "parsimonious" model that reproduces the data from the sensors used. However, in many industrial situations, the engineer develops models and simulations in the environment of a code comprising a mesher, a solver, pre-...
