We use two complementary modeling approaches for the simulation of columnar growth in directional solidification of organic alloys: a phase field model and a mesoscopic envelope model of dendritic growth. While the phase-field method captures the details of the dendritic structure and of the growth dynamics, the mesoscopic model approximates the complex dendritic morphology by its envelope

A mesoscopic description of surface chemical reactions, aimed to provide a link between microscopic lattice models and reaction−diffusion equations, is formulated.

Based on an analysis of sequential train delays, a mesoscopic train state prediction model is developed which can be used to predict the behavior of the system Macroscopic and mesoscopic models on the other hand, capture traffic mesoscopic-microscopic model that applies microscopic simulation to areas of. The deformability of soft condensed matter often requires modelling of hydrodynamical aspects to gain quantitative understanding. This, however, requires The interfacial and structural properties of fluids confined by surfaces of different geometries are studied at the mesoscopic scale using dissipative particle Mesoscopic Modeling of Ferroelectric and Multiferroic Systems. By Thomas Bose and Steffen Trimper. Submitted: October 19th 2010Reviewed: March 11th Mesoscopic modelling allows a level of detail greater than a strategic model. All software houses recognised the need for a software package that sits between 22 Oct 2020 In this paper, a three-dimensional (3D) cascaded lattice Boltzmann method ( CLBM) is implemented to simulate the liquid–vapor phase-change 31 May 2020 AbstractA point-based modeling scheme for the mesostructure of a two-step three -dimensional (3D) braided composite is proposed. The yarn 9 Nov 2020 Mesoscopic traffic flow models were developed to fill the gap between the family of microscopic models that describe the behavior of individual Three-dimensional mesoscopic modeling of equiaxed dendritic solidification in a thin sample: effect of convection flow.

Different from the traditional mesh-based modeling scheme, more complicated and more realistic profiles for the yarns can be easily built, and the material points of the matrix can be easily inserted to the reinforced structure in a uniform way. A mesoscopic description of surface chemical reactions, aimed to provide a link between microscopic lattice models and reaction−diffusion equations, is formulated. Whereas average properties derived from its constituent materials describe macroscopic objects, as they usually obey the laws of classical mechanics, a mesoscopic object, by contrast, is affected by thermal fluctuations around the average, and its electronic behavior may require modeling at the level of quantum mechanics. While the phase-field model resolves the detailed growth morphology at the microscale, the mesoscopic envelope model describes a dendritic grain by its envelope.

Michael Marsico, Andrew Weeks, Keir Opie and Murat Ayçin explain the application of hybrid traffic simulation to a planning study in New York City. Traffic modelling, particularly mesoscopic-microscopic hybrid simulation, has played a key role in planning for the future of one of America's shortest interstates, the 1.3-mile Sheridan Expressway.
