“…On the other hand, as reported in [16], filtering can amplify pressure oscillations due to the interaction with thermodynamic non-linearities, particularly across the pseudo-boiling line. Even though increasing the order of the filter obviously leads to a less dissipative filter, here the stencil is limited to a four-point function for efficiency purposes; indeed, increasing the stencil width is known to significantly deteriorate parallel computational performances, especially when dealing with implicit spatial schemes [54]. Methods of this class (although of higher spatial order) have been previously used for supercritical simulations in, e.g., [55].…”

“…From there on, the simulation runs in parallel, i.e., agents being executed simultaneously in time. To do this, the solution that has been developed considers the problems regarding overlap surfaces [37], ghosts agents [38], and agents synchronization. Further details about the spatial partition optimization process are beyond the scope of this paper.…”

In this paper, the Camp Nou stadium is used as a testbed for City Physiology, a theoretical framework for urban digital twins. With this case study, the modularity and adaptability of the framework, originally intended for city-scale simulations, are tested on a large facility venue. As a proof of concept, several statistical techniques and an agent-based simulation platform are coupled to simulate a crowd in the stadium, and a process of four steps is followed to build the case study. Both the conceptual (interdomain) and technical (domain specific) layers of the digital twin are defined and connected in a nonlinear process so that they represent the complexity of the object to be simulated. The result obtained is a strategy to build a digital twin from the domain point of view, paving the way for more complex, more ambitious simulators.

“…Kim and Sandberg 28 then developed the idea to decouple the compact scheme for parallel computations. [44][45][46] Recently, a similar approach was adopted by Capuano et al 47 in developing a parallel compact finite-volume scheme, who used a fourth-order explicit scheme and cell overlapping to decouple the compact scheme. Furthermore, Kim and Sandberg 28 proposed a decoupled sixth-order compact filter with a prediction-correction procedure.…”

“…They also discussed the effect of the number of ghost nodes, and eventually adopted one level of ghost nodes in DNS of boundary layer flows. [44][45][46] Recently, a similar approach was adopted by Capuano et al 47 in developing a parallel compact finite-volume scheme, who used a fourth-order explicit scheme and cell overlapping to decouple the compact scheme. Conservation is enforced by another application of the compact formula around interdomain interfaces.…”

Summary An improved domain‐decoupled compact scheme for first and second spatial derivatives is proposed for domain‐decomposition‐based parallel computational fluid dynamics. The method improves the accuracy of previously developed decoupled schemes and preserves the accuracy and bandwidth properties of fully coupled compact schemes, even for a very large degree of parallelism, and enables the Navier‐Stokes equations to be solved independently on each processor. The scheme is analysed using Fourier analysis and error analysis, and tested on one‐dimensional wave‐packet propagation, a two‐dimensional vortex convection problem, and in the direct numerical simulation of the three‐dimensional Taylor‐Green vortex problem and turbulent channel flow. Our results demonstrate the scheme's effectiveness in performing direct numerical simulation of turbulence in terms of accuracy and scalability.
