  A local multiple proper generalized decomposition based on the partition of unity 

  Ibáñez Pinillo, Rubén; Abisset Chavanne, Emmanuelle; Chinesta Soria, Francisco; Huerta, Antonio; Cueto Prendes, Elias (John Wiley & sons, 2019-10-12)
  Article
  Open Access

  It is well known that model order reduction techniques that project the solution of the problem at hand onto alow-dimensional subspace present difficulties when this solution lies on a non-linear manifold. To overcomethese ...
• A regularised-adaptive Proper Generalised Decomposition implementation for coupled magneto-mechanical problems with application to MRI scanners

  Hybrid coupling of CG and HDG discretizations based on Nitsche’s method 

  Spina, Andrea la; Giacomini, Matteo; Huerta, Antonio (Springer, 2020-02)
  Article
  Open Access

  A strategy to couple continuous Galerkin (CG) and hybridizable discontinuous Galerkin (HDG) discretizations based only on the HDG hybrid variable is presented for linear thermal and elastic problems. The hybrid CG-HDG ...
