El método high order Discontinuous Galerkin genera soluciones muy precisas al aumentar el orden polinómico dentro de cada elemento. Incluso cuando la solución deseada requiere sólo los modos de bajo orden de la misma, estos todavía se ven afectados por los modos de alto orden y por lo tanto no pueden ser despreciados. El efecto de estos modos de alto orden puede verse como un término fuente en un problema en el que sólo se considera la solución de bajo orden. El autor propone modelar el término fuente con una red neuronal y obtener una evolución precisa de los modos de bajo orden con menos grados de libertad y menos restricciones de paso de tiempo con el objetivo de reducir el coste computacional de las simulaciones. En este trabajo de fin ...
