Article “3D Geological Modeling Based on Boreholes Data”

Mar 18, 2013

Introduction

3D geological modeling is a very actual issue nowadays in building development, environmental assessment of soil (variably-saturated porous medium) pollution, assessment of mineral deposits, etc. There are different approaches to solve this problem by means of modern software designed for simulation in geology [1-3]. The most frequently used method is that of reconstructing geological model. This method is based on information about the levels of geological horizons occurrence received from the results of drilling [4-6]. The implementation of this method itself may have some peculiarities.

Regional IT-Conference SolIT-2013

Feb 01, 2013

Simmakers with 3 presentations took part in the Regional IT-conference SolIT 2013, which was held on January 26-27 in Soligorsk. Representatives of Russian, Belarus, German, US and UK companies participated in this event. Simmakers had invited technical specialists of such companies as “Belaruskali”, “Trest Shakhtospecstroy” and “Soligorsk Institute for Problems of Resource’s Saving with Experienced Production” to hear the presentations.

The contents of the presentations are the following:

“Computer simulation and scientific software development”. IT section. The use of computer simulation to improve product quality, manufacturing efficiency and competitiveness of the enterprise. Technological and physical processes simulation in the following areas: machinery construction, environment, mining industry. The process of scientific software development by example of creating software for simulation of heat and moisture transfer in soil under the influence of thermal load of buildings, constructions and cooling devices.

Article “Fast Volume Computing Algorithm…”

Sep 26, 2012

Introduction

Computing of the volume of polyhedron in 3D space isn’t a trivial problem, but the following trivial method exists: dividing the volume into simple pyramids and counting the sum of these volumes. However, this methodology is difficult for implementation, as well as it is resource-intensive and slow. What is more, computing algorithm according to this methodology is difficult to parallelize. And taking into account trends in the field of parallel computing on GPU development, the ability to increase the rate of computing repeatedly is being lost.

In this article the algorithm for determining the volume of arbitrary geometry in 3D space in terms of fast computing is described.

Article “Alternate directions implicit scheme and …”

Jun 14, 2012

The ADI (alternate directions implicit) method is widely used for the numerical solution of multidimensional parabolic PDE (partial differential equations). [1]. Although the method is known for a long time and is well described in the text-books, its practical realizations sometimes appear to be inaccurate [2]. The inaccuracy arises every time when one neglects the correct account of the so-called intermediate boundary conditions. This neglect can become the cause of instabilities even when the used ADI-scheme is known to be unconditionally stable in the frame of von Neumann spectral analysis technique [3]. The procedures of a correct account of the intermediate boundary conditions (for the Peaceman-Rachford ADI-scheme), are described in [4, 5, 6].
