The last equation is efficiently solved by considering a separated representation within the proper generalized decomposition framework that allows circumventing the so-called curse of dimensionality. Finally, model parameters can be added as extra-coordinates in order to obtain a parametric solution of the model2015http://zaguan.unizar.es/record/4656410.3390/e17041896http://zaguan.unizar.es/record/46564oai:zaguan.unizar.es:46564ENTROPY 17, 4 (2015), 1896-1915byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
