A critical issue in computer simulation is quality of mesh refinement in object discretization. In an already published article “FAQ for the updated version of Frost 3D Universal software”, we discussed why such large computational meshes are important.
In this article we analyze the quality of model discretization. For our example, we used ice layers beneath a 1-km model of an oil pipeline on permafrost. The 3-D model was discretized into various cell quantities using different versions of Frost 3D Universal.

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