Simmakers Active Leisure Time

Jul 31, 2014

In our company, a lot of attention is paid to healthy lifestyles, sport and outdoor activities. That means we’re looking for brand-spanking new ideas and solutions, not only in technical aspects, but also in the field of corporate governance. We believe that the creation of leading high tech solutions is impossible without good spirit, positive attitude and a smile on the faces of our employees.

Article in the Peer-Reviewed Journal “Applied and Computational Mathematics”

Aug 23, 2013

The article “Consistency of the Douglas–Rachford splitting algorithm for the sum of three nonlinear operators: application to the Stefan problem in permafrost” was published in the peer-reviewed journal Applied and Computational Mathematics Vol. 2, No. 4, August 2013.

Abstract: Consistency of the Douglas–Rachford dimensional splitting scheme is proved for the sum of three nonlinear operators constituting an evolution equation. It is shown that the operators must be densely defined, maximal monotone and single valued on a real Hilbert space in order to satisfy conditions, under which the splitting algorithm can be applied. Numerical experiment conducted for a three-dimensional Stefan problem in permafrost suggests that the Douglas–Rachford scheme produces reasonable results, although the convergence rate remains unestablished.

Numerical experiment, conducted for 3D Stefan problem in permafrost indicates that Douglas-Rachford algorithm gives reliable results, although the convergence rate remains unknown.

Article “The Transfer of Boundary Conditions on an Orthogonal Hexahedral Mesh”

Aug 02, 2013

In the simulation of physical processes and phenomena overall there is a problem of numerical solutions of differential problems in partial derivatives. One of the methods for numerical solutions of mathematical physics equations is the approach, based on the finite difference approximation. However, the major drawback of this method is the need to use orthogonal hexahedral mesh. While solving problems in practice, sometimes a complex geometric configuration of the computational domain (for example, see Figure 1) is used, and therefore, the drawback, mentioned above, is enough critical.

The World Congress on Engineering, 2013

Jul 15, 2013

On 3-5 July, 2013 The World Congress on Engineering took place in London, United Kingdom.

Simmakers took part in the Congress and represented the report:

Quasilinear Heat Equation in Three Dimensions and Stefan Problem in Permafrost Soils in the Frame of Alternating Directions Finite Difference Scheme

Abstract — The quasilinear heat equation with thermal conductivity and heat capacity depending on the temperature field in three spatial dimensions is studied in application to the phase transition problem in permafrost soils. The conditions under which the alternating directions Douglas – Rachford finite difference scheme retains numerical stability are explicitly formulated. The comparison with the known analytical similarity solution to the Stefan problem in one spatial dimension is performed.

Index Terms — quasilinear heat equation, Stefan problem, finite differences, alternating directions scheme, numerical stability.
