1. A computer implemented method for obtaining a model of data describing a physical structure, the method comprising: defining a three-dimensional (3D) object that corresponds to a physical structure, the 3D object comprising a set of topological elements that each has an initial geometric definition; defining a subset of topological elements, which is less than an entirety of the set of topological elements, using an enriched finite element modeling (EFEM) technique; and using a computer to create a subsequent model of the data by updating the subset of the topological elements defined using the EFEM technique in the 3D object, each updated topological element in the subset of topological elements having a geometric definition that has changed relative to its initial geometric definition.
