A high-order central essentially non-oscillatory (CENO) finite-volume scheme in combination with a block-based adaptive mesh refinement (AMR) algorithm is proposed for solution of hyperbolic systems conservation laws on body-fitted multi-block mesh. The CENO based hybrid reconstruction procedure that combines an unlimited k-exact least-squares technique following from fixed stencil monotonicity preserving limited piecewise linear algorithm. Switching the determined by smoothness indicator...
A high-order, central, essentially non-oscillatory (CENO), finite-volume scheme in combination with a block-based adaptive mesh refinement (AMR) algorithm is proposed for solution of the Navier-Stokes equations on body-fitted multi-block mesh. In contrast to other ENO schemes which require reconstruction multiple stencils, CENO method uses hybrid approach based fixed central stencil. This feature crucial avoiding complexities associated stencils schemes, providing high-order accuracy at...
and scalable cubed-sphere grid framework is described for simulation of magnetohydrodynamic (MHD) space-physics ows in domains between two concentric spheres. The unique feature the proposed formulation compared to existing codes lies design a that based on genuine consistent multi-block implementation, leading ux calculations, adaptivity, implicit solves, parallelism are fully transparent boundaries six root blocks correspond sectors grid. Crucial elements approach facilitate this exible...
Abstract The article aims to highlight the usefulness of composite indicators applications as an analytical tool in guiding national security policies related multidimensional phenomena revealing its role measuring hybrid threats - part global risks. qualitative and quantitative research shows that use at country level is a relatively new topic, has enjoyed increased interest since 2021. originality lies way it putted evidence link between nature threats, order argue using this modern...
A “dirty bomb” is a type of hypothetical radiological dispersal device (RDD) that has been the subject significant safety and security concerns given disruption would result in postulated terrorist attack. Reliable accurate predictions dispersion material from an RDD are absolutely necessary for first responders emergency decision makers to plan effective response strategies. Development high-fidelity, mechanistic models dirty bomb complicated because over areas with greatest risk...
