“…Sources [3] and [4] presented the results of simulating the thermal and stress-strain behavior of several reflector variants with the concave shell ribbed reinforcement for the geostationary Earth orbit (GEO) conditions, which proved the possibility of the designs with the small linear density and high stiffness [4]. After the analysis of various reinforcement patterns [5], the "five-point star" pattern was singled out, as being superior to the other variants with respect to stiffness and linear density.…”

Abstract. Parabolic three-layered reflectors from polymer composite materials with the aluminium honeycomb fillers became widely used in space communication systems in the past decades. There are technological possibilities for creating reflectors in the form of thin-walled ribbed shell with the lower linear density than that of the three-layered structures. The paper presents the results of the temperature and stress-strain analysis for the two types of structures, which could help to select the variant with the best performance characteristics.

The paper presents a mathematical model of a finite element for modeling imperfect interface conditions for two contacting surfaces. The element is used in the numerical implementation of the Asymptotic Averaging Method (AAM) for the determination of effective elastic properties of composite materials under investigation. Numerical experiments are carried out to calculate the elastic properties taking into account the adhesion layer using a displacements field jump condition at the phase boundary. Results are compared with adhesion modeling using an additional bulk phase.

“…Development of unified computer-aided software packages for generating adaptive grids currently represents a large-scale problem of applied mathematics, computational physics, mechanics, biology and medicine [1][2][3]. Existing open-source and commercial software packages mainly use mesh generation methods that are universally applicable for complex geometry and focus on the generation of unstructured finite element or finite volume grids [4][5][6]. Structuring and adaptation of a mesh, as well as the hexahedral shape of its cells, usually can be held only near some boundaries of the domain.…”

The paper covers the area of block-structured adaptive grid generation for finite difference, finite element and finite volume methods. It deals with a problem of development of information technologies and algorithms for generating such grids in complex geometries. Its key idea is to bring together the different existing techniques for computer-aided geometric design of domains, grid generation, grid concentration and grid subdivision. The methods used for a construction of domain geometries, working with block-structured quasi-continuous grids, a subdivision of block-structured adaptive grids into vertex-centered control volumes, generation of ghost nodes and cells, calculation of distances to boundaries are discussed. It is described of the software interfaces of the geometry editor and the mesh generator that were developed in the SIGMA preprocessor. The results of the generation of three-dimensional adaptive grids for the domain of external flow near a hemisphere, flow around a surface of the high-speed aircraft of Falcon HTV-2 type and for the domain of the gap between a wheel and a body of an aircraft are analyzed. The presented methods and algorithms for grid generation have the following advantages: 1. The grids are structured and mesh cells are hexahedra in the entire complex curvilinear computational domain. 2. The grids can be applied for finite difference methods. 3. The grid lines are adjusting with the flow in the whole domain. Keywords-block-structured adaptive grid, finite difference grid, computer-aided geometric design, complex domain, mesh subdivision, preprocessing
