To this end, different machine learning (ML) techniques are combined to create surrogate models of numerical simulations in which the domain depends on the input parameters and the discretization grid is not known a priori. Among the advantages of the invention are the highly reduced computation times as compared to those required for the numerical resolution of the equations of the model while maintaining a high accuracy of the estimate.
