Parallel multi-core and multi-processor methods on point-value multiresolution algorithms for hyperbolic conservation laws
TL;DR: The performance yielded through the new concept of multiresolution forest structures indicates that the MFS is a new headway for the MR method in parallel computing that has a potential to harness better scalability.

On the accuracy and efficiency of point-value multiresolution algorithms for solving scalar wave and Euler equations
TL;DR: This paper concerns the use of a point-value multiresolution algorithm and its extension to three-dimensional hyperbolic conservation laws and a new tolerance-scale diagram is introduced to assess the efficiency and the accuracy of the method.

TL;DR: In this paper, the effects of the change of the geometry of the concave surfaces and the incident shock wave Mach numbers on the overall behavior of shock wave reflections were investigated. But the authors focused on the effect of the impact of the Mach number on the reflection over different geometries of concave surface.

Shock-wave reflections over double-concave cylindrical reflectors
TL;DR: In this paper, numerical simulations were conducted to understand the different wave configurations associated with the shock-wave reflections over double-concave cylindrical surfaces, where the reflectors were generated computationally by changing different geometrical parameters, such as the radii of curvature and the initial wedge angles.
Analysis of shock-wave diffraction over double cylindrical wedges. Part II: Vorticity generation
TL;DR: In this article, the effect of the first concave surface on the shock strength has been quantified at both earlier and final stages of the shock diffraction process, and the results show that the diffusion of the vorticity due to viscous effects is quite important compared to the baroclinic term for low Mach numbers regimes.
