Article “3D Computer Simulation of Ground Thaw Bulb Formations Including Ice Wedges Around the Pipeline”

Jun 05, 2014

The article “3D computer simulation of ground thaw bulb formations including ice wedges around the pipeline” was published in the industry-specific journal ”Pipeline transportation: theory and practice” (# 6 (40) 2013).

The main threat to the integrity of the underground pipeline is the ground settling under it, caused by the thawing of ice wedges. In the article, ground freezing and thawing with ice wedges around various pipeline intersections are numerically simulated with Frost 3D Universal software. The obtained results provide crucial data for the feasibility analysis of the pipeline construction, the pipeline route plan and subsequent evaluation of potential problems during operation.

Record-breaking Achievements in the Frost 3D Universal Software: Simulation of a Lengthy Section of a Gas Pipeline

May 13, 2014

Prediction of the ground thaw formations around a kilometer-long section of a relatively long gas pipeline was implemented for the first time on a model discretized in 58 million nodes in the newest version of Frost 3D Universal software. Simulations of the ground thaw formations around the gas pipeline were performed for a 2-year period. For the computations, a PC with a quad-core CPU and 24 GB of RAM was used. The computation in Frost 3D Universal software was completed within 68 hours. The approximate computation time of the given model using the Tesla К40 video accelerator is 8 hours.
