  • Increase speed of calculation of stress-strain state by method of discrete elements

    The article describes a software complex based on the software system of formation and solving of nonlinear dynamics equations to calculate the stress-strain state of the model by discrete elements. Steps of the method found suitable for acceleration using parallel computing. The results of the testing of a modified software package are presented. A general 2.4 times acceleration of method implementation was achieved.
