Performance Comparison: Intel Core i7 and Graphics Card Nvidia Titan

Nov 13, 2014

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.

Application of ANSYS for Thermal Analysis of Permafrost Soils. Advantages of Frost 3D Universal

Jun 23, 2014

An engineering company has recently asked Simmakers to comment on the possibility of applying the finite-element package of ANSYS to the problems of ground thawing and thermal stabilization, and to explain the advantages of Frost 3D Universal software when solving such problems. Note that this issue has also been addressed by various specialists in dedicated forums, and conferences.

 

Mathematicians and experts in the field of thermal analysis and numerical simulation gave comprehensive comments regarding the advantages of Frost 3D Universal over Ansys for computer simulation of ground freezing and thawing problems.

FAQ for the New Version of Frost 3D Universal Software

Jun 12, 2014
After releasing the article “Thermal analysis of a lengthy section of a gas pipeline on permafrost” on our blog, we received questions from users, concerning the latest version of Frost 3D Universal software.

We would like to reiterate that the new 64-bit GPU version of Frost 3D Universal software was released in May, 2014. In this version, technological innovations were implemented which enabled the computation of computational meshes as large as 100 million nodes on a PC. The simulation model was demonstrated with the thermal analysis of a long section of pipeline lying on permafrost, with a mesh consisting of 58.5 million nodes.

Nvidia Tesla K20 vs Intel Core i7: Speed Comparison

Jan 24, 2014

Simmakers Ltd, together with Nvidia and Forsite have tested the speed of a GPU version of the Frost 3D Universal software package for solving heat transfer problems on the Nvidia Tesla K20 system. The results have exceeded all expectations — the computation for an ice wall around the Fukushima Nuclear Power Plant was completed in under 6 minutes.

In order to carry out a detailed comparison of the computational speeds on systems with different configurations, Simmakers prepared special tests that included the following model dimensions:

1) 1 million cells (100x100x100);

2) 3.4 million cells (150x150x150);

3) 8 million cells (200x200x200);

4) 15.6 million cells (250x250x250);

5) 27 million cells (300x300x300);

6) 42.9 million cells (350x350x350);

7) 64 million cells (400x400x400);

8) 91 million cells (450x450x450).
