Simmakers Ltd. at the V Regional Conference Solit

Mar 20, 2015

Simmakers Ltd. participated in the V Regional Conference Solit, which was held on March 14-15, 2015 in Soligorsk.

As in previous years, the conference was organized into 3 simultaneous sessions: seminars, connected with programming; talks, devoted to IT topics in general; talks and events with a semi-IT focus. To relieve conference stress, participants were able to enjoy such events as Geek Fest, CoachPit, Mashpit, XXX2Dev meetup, IT career and regional start-ups events.


Frost 3D Universal Verification: Numerical Computation, Analytical Solution and Experimental Data

Mar 03, 2015

The mathematical model used in Frost 3D Universal has been verified against the precise analytical solution to the soil freezing problem and against experimental data obtained under laboratory conditions.

The results demonstrate the high accuracy of the numerical solutions obtained by the Frost 3D Universal software package. Comparison of the software’s numerical computations with exact analytical solutions shows that the error does not exceed 0.5%, and this figure approaches zero in Frost 3D Universal as the spatial step decreases.

Analysis of Foundation Deformation and Subsidence

Jan 19, 2015

The R&D Department of Simmakers Ltd. has introduced an article on the computer simulation of foundation deformation. The approach is based on numerical solution of the stationary differential equation in partial derivatives. This method allows you to predict the behavior of foundation and soils, taking elasticity and boundary conditions into account, enabling accurate simulation of subsidence.

In an already published article, we consider the main types of foundations on subsiding soils: the case when foundation is fastened to the raft and the case when the foundation slab rests on the ground surface or piles.

Simulation of a road in permafrost area

Road design in permafrost areas requires a special approach based on the thermal analyses of soil foundations and roadbeds to determine the necessary design parameters of the road, such as the height of embankment, the thickness of the thermal insulation layer, etc.


Implementation of Alternate Direction Implicit Method with CUDA

Nov 26, 2014
Simmakers specialists have analyzed the efficiency of applying CUDA technology to the implementation of the Douglas-Rachford scheme (alternating direction implicit method, ADI method). The ADI method is used to solve partial differential equations of the parabolic type, such as heat equations in three dimensions. It was found that the Douglas-Rachford scheme presented natural parallelism allowing for effective ADI mathematical solver parallelization with CUDA (Nvidia).

In the article, we provide calculation results demonstrating the performance acceleration for software-implemented Douglas-Rachford scheme using CUDA technology when compared with the implementation of the same scheme on a CPU.


Performance Comparison: Intel Core i7 and Graphics Card Nvidia Titan

Soil thermal field distribution over 5 years in the XZ plane

Experts from Simmakers conducted a comparative performance analysis of hardware computational modules – Intel Core i7 CPU and GeForce GTX Titan graphics card, using the thaw bulb simulation model around a well cluster.

To evaluate the efficiency of parallel architecture in thermal analyses (characteristics of the computational processors aside), the degree of the computational mesh detail is dramatically important. Therefore, the three-dimensional model was discretized with different spatial steps in the tests. As a result, meshes with the next number of nodes were obtained: ~2 million, 4 million, 8 million and 16 million. Each computational mesh was computed on 1 core of Intel Core i7, 4 cores of Intel Core and a GeForce GTX Titan video card.


Conference “Technologies for Foundation Design and Construction on Permafrost”

Oct 20, 2014

On October 16, 2014 experts from Simmakers Ltd. gave presentations at the “Technologies for design and construction of foundations on permafrost” conference, as part of the CityExpo exhibition.

The conference was organized by the International Association of Foundation Contractors (IAFC), one of the leading promoters of professional and technical development in foundations engineering for construction companies and specialists in Russia and abroad.

The conference focused on topics such as design and construction of bases and foundations on permafrost, the installation of foundations in permafrost areas, oil and gas pipelines on permafrost, thermal stabilization of soil bases of buildings and structures, temperature monitoring systems in permafrost, etc.
