The computational mesh module, developed for 64-bit CPU architecture, is now based on.
Equations for creating the computational mesh.
The computational mesh on which the calculation was performed contained 17 828 087 spatial nodes.
Question: Why do we need such large computational meshes?
This is simply not enough for large computational meshes where computation is based on very large matrices processing.

How did you manage to create a computational mesh of 58 million cells in Frost 3D software?
Let the computational domain be a parallelepiped, and the computational mesh of nodes set.
Each computational mesh was computed on 1 core of Intel Core i7, 4 cores of Intel Core i7 and the GeForce GTX Titan video card.
Let's analyze a cylinder that constitutes a finite computational mesh with voxels.
We now construct a computational mesh with approximately the same number of nodes using the adaptive step, with refinement in the center.
The increase in the cell size in irregular computational meshes needs to be very smooth;
According to designations,the following set of points is the set nodes of computational mesh.
Question: It is well-known when increasing the number of cells in the computational mesh, we obtain a significant increase in computational time.
The specific nature of the current problem- simulation of the ground thaw formation along a 500-meter section of the oil pipeline, 1.2 meters in diameter-rendered a large computational mesh necessary.
Note that even with the use of a non-uniform cell size(at irregular computational mesh), for example, we still need a lot of nodes.
Thus, in order to generate correctly a computational mesh it is necessary to solve the problem of intersections and overlapping of geometric objects(collision problem of geometric objects) manually, i. e.
The 3D visualizer of computational results, developed for 64-bit CPU architecture and graphics cards,now preprocesses the computational mesh by forming a hash data structure.
Answer: 32-bit versions of the software couldn't handle computational meshes like this due to the limitations of the operating system which can only address 4GB of RAM.
This will quickly and correctly process collisions cases of two or more geometric objects(Figure 1)when performing cells marking of the computational mesh by means of geometric objects.
Preparation of the model(preparation of geometry and computational mesh, definition of physical and material model, determination of limiting conditions etc.), the second consists of the calculation itself(Solver) and the final involves post-processing, i. e.
Question: Why not create a coarser mesh and reduce the number of elements by several times; therefore,you won't need such large computational meshes and the computation itself would be faster?
Despite the fact that the computational complexity of the preprocessing phase is, and with the modification is added as well, it is necessary to considerthat this is done only once and not for each cell in the computational mesh.
Numerical solution of the problem wasimplemented in Frost 3D Universal software, with a computational mesh of 58.5 million nodes, to predict ground thaw under the influence of the pipeline.
Thus, in order to obtain a quality, detailed discretization of the pipeline while also taking into account both the complex geological-lithological structure of the grounds and the fine heat insulation material,we built a large computational mesh with 58.5 million nodes.
It means that the maximum acceleration on parallel architectures couldbe achieved on the simplest models with a uniform computational mesh and the minimum number of materials and boundary conditions.
As can be seen from the above,we have described a mathematical model of the development of configurationally complex computational mesh, consisted of voxels that are situated on a sheet and twisted into cylinder.
