Specialists of Simmakers Ltd. have introduced an article about new numerical simulation method of transient heat transfer. The last is based on spatial interpolation of soil temperature from temperature logs of monitoring wells.
In this new article, the R&D Department of Simmakers Ltd. focus on the modification of the Douglas – Rachford ADI scheme to account for convection in the computational domain.
The annual team retreat has become a good tradition of our company. A healthy lifestyle, outdoor activities, a positive state of mind and sense of well-being is what, in addition to high qualification of our specialists, allows us to develop unique software. A year ago the employees of our company climbed the mountains and experience rafting and this year they move across the Sahara desert.
The design of a frozen dam is impossible without thermal analyses in relation to architecture, the thermophysical properties of the soil, and meteorological and hydrological conditions.
The most effective tool for such simulations is the Frost 3D Universal software package that enables you to forecast soil freezing and thawing with regard to groundwater filtration.
Simmakers Ltd participated in the XV scientific conference “Information Technologies in Engineering”, held on 7-8 April 2015 at Giprotyumenneftegaz (R&D and engineering company, Tyumen, Russia).
As usual, the conference was attended by leading R&D institutes involved in the oil and gas industry: Giprovostokneft, Lukoil Engineering, SurgutNIPIneft, as well as software solutions vendors: Bentley Systems, ANSYS, CSoft and others. Among the conference participants were some of Simmakers Ltd customers: Fundamentstroyarkos, Tyumenneftegazproekt and our partners from NVIDIA.
The conference focused on topics such as new IT solutions, computer simulation technologies and the use of CAD and CAE systems in the oil and gas industry.
The article “Forecasting of Permafrost Thawing Around an Underground Cross-Country Pipeline” was published in the peer-reviewed scientific journal “Oil&Oil Products Pipeline Transportation: Science and Technologies” (№ 1 (17) 2015).
In the article, formation of thawing bulb around the cross-country pipeline is simulated in Frost 3D Universal software package. Presented computer simulation is based on the numerical solution of the heat equation in three-dimensional statement factoring phase transitions. The proposed technique can be applied at design and operation of underground pipelines in difficult geological and engineering conditions for an assessment of the thawing bulb formation. The knowledge of the thawing bulb size is necessary at calculation of the stress-strain state of a pipeline.
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.
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.
