ReducedBasis

ReducedBasis.jl is a Julia package that uses the reduced basis method to accelerate the solution of a parametrized eigenvalue problems across the parameter domain.

In the RBM approach, a surrogate model is assembled by projecting the full problem onto a basis consisting of only a few tens of parameter snapshots. The package focuses on a greedy strategy that selects snapshots by maximally reducing the estimated error with each additional snapshot. Once the RBM surrogate is assembled, observables or post-processing can proceed at any parameter value with only a modest complexity scaling independently from the dimension of the initial eigenvalue problem.
