In this paper, the problem of numerical modeling of thermoelastic behavior of nose caps of hypersonic vehicles at different angles of attack is considered. 3D finite element modeling is performed by solving the coupled heat and elastic problems taking into account thermal and mechanical properties variations with temperature. A special method for calculating the aerodynamic heat flux entering the...
This work describes the application of modern high-performance computing technologies such as multicore CPUs and GPUs coprocessors to the solution of three-dimensional (3D) problems of geoelectromagnetism with the use of the finite element method. The techniques for speeding up sparse linear system solving via iterative methods are discussed. Programs to solve large sparse complex-valued linear systems...
The paper considers the software which implements the geometric-2D inversion of induction logging data in vertical wells. In solving the direct problem the electromagnetic field simulation is carried out by the finite element method in cylindrical domain. As unknown parameters which are to be recovered during the inversion, we take the values of conductivity, the horizontal boundaries of the layers...
