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

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.

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.

Yuri Shprits’ Project Awarded EU Innovation Grant

Sep 22, 2014

Sept 22, 2014

The EU commission Horizon 2020 has been awarded to a team led by Managing Partner of Simmakers Ltd, Professor Yuri Shprits. The project is scheduled for implementation within 3 years.

Professor Yuri Shprits and his team of researchers are working on the creation of new services for high accuracy space weather forecasting (based on moving electron streams and radiation belts). The aim is to develop methods for more precise geomagnetic indices forecasting. The research is based on numerical methods and modern computer simulations that allow satellites to behave as navigators.

Calculation of Foundation Settlement on Permafrost Grounds

Sep 17, 2014

Sept 26, 2014

Calculation of soil settlement is one of the main tasks of applied computer simulation in construction. This allows the simulation of the settlement of bases and foundations under different maintenance conditions over time, evaluation of the complexity and construction costs, reliability and durability.

In permafrost regions settlement, can be caused not only by structural loads, but also by ground thawing, resulting from the additional pressure of ground transition from frozen to thawed states.

This article describes the method of settlement calculation according to SNIP 2.02.04-88.

Frost 3D Universal Versions and Hardware Comparison

Sep 08, 2014

Sept 8, 2014

There are 4 versions of Frost 3D Universal:

  • 32-bit, single core CPU
  • 64-bit, single core CPU
  • 64-bit, multicore CPU
  • 64-bit, multicore GPU

 

The main differences between versions are the speed of the mathematical solver and the number of cells for model discretization.

Frost 3D Universal Versions And Hardware Comparison

The speed of numerical computation depends on the computer configuration (number of CPU cores), and video card performance (GPU versions of software).

As a result, the question “Which version of Frost 3D Universal could fulfil users requirements?” often arises.
