TL;DR: In this paper, a minimum weight with stress constraints Finite element formulation for the topology optimization of continuum structures is proposed, where the material mass is restricted to a predefined percentage of the maximum possible mass, while no displacement constraints are taken into account.

TL;DR: This paper explores the feasibility of defining a so-called global constraint, which basic aim is to limit the maximum stress simultaneously within all the structure by means of one single inequality, and compares the performance of these three approaches by solving several topology optimization problems.

TL;DR: This paper explores the approximation power of Moving Least-Squares approximations in the context of higher-order finite volume schemes on unstructured grids and proposes a selective limiting procedure, based on the multiresolution properties of the MLS approximants, which allows to switch off the limiters in smooth regions of the flow.

TL;DR: In this paper, the authors explored the approximation power of Moving Least Squares (MLS) approximations in the context of higher-order finite volume schemes on unstructured grids.

TL;DR: This work introduces a numerical method based on isogeometric analysis that couples the discrete and continuous descriptions of the theory of tumor angiogenesis and performs numerical simulations that show the development of the vasculature around a tumor.
