The code performs nonlinear model order reduction of Finite Element models using the direct parametrization method for invariant manifolds

It implements the theory developed in:

Alessandra Vizzaccaro, Giorgio Gobat, Attilio Frangi, Cyril Touzé, Direct parametrisation of invariant manifolds for generic non-autonomous systems including superharmonic resonances, arXiv preprint arXiv:2306.09860

and in several previous publications.

Link to the 2D version: DPIM2D

It uses the freeware code gmsh as pre and post processor and MatCont for the continuation of periodic solutions
