Detailed Description

template<int dim>
class SIM::DakotaLeastSquaresInterface< dim >

This class is used to solve a least-squares parameter estimation problem.

Data is read in from file and the solve function loops over the data points and obtains a solution from the fuel cell simulator. The results are returned to DAKOTA for the optimization loop.
