Dear Sirs,
I would like to have an opinion by more expert users than me. I am facing a problem of parameter estimation by inverse analysis for structural mechanics. More simply, I have to estimate the values for certain parameters of the constitutive law. The observation variable that I look at in order to understand if the current value of the parameter is correct is the displacement field in the domain.
The mathematical formulation of the problem involves a functional J that should be minimised and the so called primal and dual problems.
Have some of you ever tried to solve this type of problem? If yes, which package of Comsol did you use? I think the best would be to use the Sensitivity module that is in the General PDE module but I would like to have some advice.
Many thanks for the help,
I wish you a nice day,
Paolo Tricerri
