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.

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 “Finite-Difference Approximation…”
