Abstract-Application to RCS computation of a higher order solver based on the surface integral approach is presented. The solver uses a direct method to solve the corresponding algebraic system of equations. Two versions of the solver are available: in-core and out-of-core. Both are efficiently implemented as parallel codes using Message Passing Interface libraries. Several benchmark structures are analyzed showing the reliability, performance, and versatility to run in a wide variety of computer platforms, of the solver. The results shown are illustrative of what is the maximum frequency of analysis of the structures for a given type of simulation platform.

Abstract-The aim of this work is to asses the computational performance of a finite element formulation based on nodal elements and the regularized Maxwell equations. We analyze the memory requirements and the condition number of the matrix when the formulation is applied to electromagnetic engineering problems. As a reference, we solve the same problems with the best known finite element formulation based on edge elements and the double curl Maxwell equations. Finally, we compare and discuss the computational efficiency of both approaches.

Within the cultural sector, cultural heritage presents a series of interesting features for the territorial development of the local and regional Economy. This sector presents a prevalence of wage employment and a larger size of business establishments than the rest of the services sector. While small companies and micro-companies predominate in the services sector with 99,4% in 2019, for companies related to cultural heritage, the weight of companies with less than 50 employees does not reach 97.3% for this year. Also, it is essential to highlight the legacy value that makes cultural heritage endure over time for future generations to enjoy it; it also creates awareness and territorial roots of the populations, and, finally, is a fundamental asset for tourism and branding of the territories.
