  4. The names of directors do not have to coincide with reserved names in Windows (WITH, PRN, TO, CLOCK, NO, COM1, COM2, …, COM9, LPT1, LPT2, …, LPT9 and others.).

*For a complete list of restrictions can be found on Microsoft's official website: //

It should be remembered, that the gaps at the end of the name is automatically deleted by the operating system.

Important: The program displays a list of calculations, received in the last scan calculations directory. If necessary, update the list manually, pressing the "Reload calculations" button.


2. Modeling: thermal physics, heat equation, properties, etc..

8. Q: Is it possible to take into account temperature changes within one of the day / hour at setting temperature versus time in the boundary condition / external environment? for example: within one day temperature 12:00 = 0 ° C, and 13:00 = 100 ° C?

A: The software package allows you to take into account the change in dependency on time with a resolution of up to 1 seconds. Nevertheless, we recommend not set values ​​change in increments, lower, than 1 time.


9. Q: Can I use the date of the measurement of the depth of soil temperature distribution, as the start date for calculation (initial moment of the forecast period)?

A: Yes, usually, date measurements of soil temperature is taken as the start date for calculation.


10. Q: Do I need to set the dependence of physical quantities on time in the boundary conditions from the date of commencement of the simulated (projected) period of time?

A: Date of start of calculation is not influenced depending on the outside temperature, solar radiation or other physical quantities on time. All physical quantities are "tied" to the calendar and do not depend from the date of commencement of the calculation.

Important: Make, that all physical quantities depending on the time given to the all the simulated period of time.


11. Q: Can I use the constant ground temperature (throughout the depth of a constant temperature, throughout the computational domain) as the initial temperature distribution in the soil?

A: For accurate results, outlook, We do not recommend using a constant temperature as the initial temperature distribution in the soil. Given the fact, that the soil temperature varies with depth, should use data thermometric survey.

Important: For short-term forecasts (1-3 of the year), We recommend using the most accurate value of the initial soil temperature.

Constant soil temperature at the depth of use in cases, when data is missing or thermometric investigations same initial temperature distribution in the soil neglected *.

*Neglect the initial temperature distribution is possible only in a narrow class of long-term forecasts in the wild.


12. Q: What is a "calculation in vivo" and why to use it?

A: "Calculation of the in vivo" – This numerical experiment, which allows us to estimate the temperature distribution in the soil, based on the climatic information, and thermophysical properties of soils. Nevertheless, some institutions use this method to get the initial temperature distribution in the soil, what, in our opinion, It is not always acceptable because of the low accuracy of the input data (climate data and / or data thermometry).

We recommend that the "calculation in vivo" only to verify compliance with climate data thermometry data:
1. Create a three-dimensional model of geology without construction projects and technological impacts;
2. Ask climatic data;
3. Ask the approximate temperature of the whole depth. Usually, is used for the temperature characteristic of the region;
4. Perform calculations on 50-100 years.

Across 50-100 s temperature in the ground is stabilized, and will correspond to climatic conditions. The obtained temperature values ​​should be close data thermometry, obtained experimentally.


13. Q: After starting the calculation decision is stopped and the software system according to "memory error".

A: This error occurs, when the software system does not have enough RAM or VRAM for the task. The most common causes of this error are:

  1. a user erroneously indicated the value of the heat capacity of one of the materials in the "Database of materials and State". Users may mistakenly enter a value in MJ /(m3 * K) or in kJ /(m3 * K) instead of J /(m3 * K). Carefully recheck values ​​of volume specific heat of each material in the "Data Base materials and GU";
  2. computational grid contains too many nodes (cell). Reduce the number of components without loss in accuracy is possible using a computational grid markers. If the computational grid markers already placed optimally (from a user perspective) way, it is necessary to make the computational grid coarser;
  3. minimum space step computational grid is very small (less 1 cm);
  4. one of the materials of the computational grid has an extremely high thermal conductivity (more 1000);
  5. a very long period of simulated time (more 1000 years);
  6. Any combination of points 1,3,4,5, further complicates the problem and narrowing margins, indicated in the respective paragraphs. for example, reliance on 500 years through the steel wall thickness 1 cm, which is equal to the thermal conductivity 48, you can cause "memory error", tk. formulation of the problem is close to the borders, referred to in paragraphs 3,4 and 5.


3. Interface software package: use buttons, window

14. Q: How well the correct temperature into account?

Q: Perform the following steps:
1. The database of materials, physical properties and heat transfer conditions (further database) in "Thermal distribution" tab create borehole temperature and identifies some temperature dependence of the depth.

Вкладка «Тепловое распределение» Указание (задание) термометрических скважин.

Tab "Heat distribution" Note (the task) Thermometer wells.

2. The database in the "Materials" tab, set the temperature of the soil, other than temperature, predetermined temperature for the well.

3. calculations of.
The results of the calculation can not see the effect of the temperature of the well.

A: For each material in the "Material Database, physical properties and the conditions of heat exchange " (further database) You can apply only one of two methods of specifying an initial temperature:
a) Use a three-dimensional thermal distribution;
b) Use separate tabular temperature dependence of the depth.
This is due to the fact, that the ground can not have two different values ​​of the initial temperature.

Рисунок 1 – Вкладка «Материалы»: указание начальной температуры грунта.

Drawing 1 - tab "Materials": specify the initial soil temperature.

For use temperature wells to specify the start of ground temperature:
1. Add information about temperature wells in the database tab "Heat distribution";
2. The database in the "Materials" tab, select "Use a thermal distribution" for all materials, which temperature must conform to three-dimensional temperature distribution (cm. Drawing 2).


Drawing 2 - Switch thermal distribution.

3.Perform calculations.
Temperature of the soil at the initial time will correspond to a given (via temperature wells) three-dimensional thermal distribution.


15. Q: In SU on the MCS difference in temperature is set with the correct sign or modulo?

A: The temperature difference should be set positive value.


16. Q: Why change the position of one of the three-dimensional objects in the "Editor 3D» and carrying out the construction of "Clearing the grid", sample quality the displaced object was significantly lower?

A: For high-quality sampling facility in the software package used markers the estimated mesh (markers of decomposition and / or condensation). When the position of three-dimensional objects, you must also move the markers and the calculated grid, who will be involved in the construction of the estimated grid.


17. Q: How to change the position of the estimated grid markers during the "Edit 3D»?

A: The estimated position of the grid markers can only be modified in the "Editor 2D». For this, go to the "Edit 2D» (any time, to construct the estimated grid) and edit the position of the markers. Re-constructing a three-dimensional model is not required.


18. Q: How to change the position of the estimated grid markers in the "Editor 2D»?

A: On the left sidebar there is a group of buttons, which allow you to add new markers (More details in the "User's Guide", paragraph 3.1.1). Markers can be selected and edited in the list area (the right side of the screen) and on stage (area of ​​work with geometry, in the center of the screen). To view and edit the properties of the markers, select one or several properties in the area markers (bottom right).

Рисунок 1 - Свойства маркера сетки

Drawing 1 – Properties grid marker

The absolute coordinate - is the coordinate on the Z axis. note, that the units Z coordinates could differ from the coordinates of the measurement units X,Y. Often the unit of measurement for absolute marks differs from the unit of length. So, on Figure 1Z absolute coordinate marks are measured in meters, and X and Y coordinates - in millimeters.

marker type - defines the method of influence on the calculated grid marker (decomposition or condensation Markers). Thickening Markers allow you to create the calculated thickening nets near their position. Markers partitioning allows you to manually control the partition grid.

Type of positioning marker - defines the coordinate axes, which will affect marker. Possible options:

  • XYZ
  • X
  • Y
  • FROM


Refers to objects - all markers should relate to the "markers" object.

Coordinates (location) determine point marker, which will be implemented concentration (thickening of markers) or partition (to split markers) the estimated grid. for example, If positioning marker type is set to X, the condensation or decomposition will be performed only on a predetermined axis. In the construction of the estimated grid coordinates of all the other marker will be ignored. We encourage you to read a good example markers with different types of positioning in Figure 2.

Рисунок 2 – Примеры воздействия маркера сгущения на расчётную сетку

Drawing 2 - examples of the impact of condensation marker on the calculated grid

On the image 2 depicted (red) markers thickening of various types of positioning. Blue and green lines denoted Net (cell borders the estimated grid). Black lines represent the coordinate axes.

Figure 2a - thickening markers ranking type X. There is a decrease in grid spacing over the space near the X-coordinate marker. Y and Z coordinates of the markers have no effect on the calculated grid (The same effect will be achieved, if you place the marker at the position of the red circle).

Figure 2b – markers condensation type Y positioning. There is a decrease of the mesh size of the space Y near the marker coordinate. X and Z coordinates of the markers have no effect on the calculated grid (The same effect will be achieved, if you place the marker at the position of the red circle).

Figure 2c - thickening of the marker with the type XYZ positioning. A decrease in mesh size for all the coordinates.

Important: To change the parameters and / or number of markers will be displayed on the estimated net:

  • Rebuild the calculated net, pressing the "next stage" in the "Editor 3D»;
  • Check the parameters of the construction of the estimated grid.

For detailed information regarding the modes of construction of the estimated grid, be sure to check with paragraph 4.6 "Starting transfer 3D model on a computational grid" Documentation software package.

Examples of practical application of the markers set forth in the free training video course Frost 3D Universal, access to which you can request from our company's management.


19. Q: How to create a table of temperature versus depth for multiple time points?

Q: Example necessary depicted table Figure 1.

Рисунок 1 - Пример таблицы для отчёта.

Drawing 1 – EXAMPLE tables for the report.

A: Program complex Frost 3D Universal provides the ability to automatically create a table of temperature versus depth at the same time for a few moments of time. To create the specified size of the table (cm. Drawing 1), We recommend using Graph temperature along the vertical (thermometric well).

Pay attention to the following symbols:

t_{1},t_{2},...,t_{n} moments, which is necessary to obtain temperature versus depth;
n the number of time points t_{i};
V_{x,y} vertical line in three-dimensional space, which coordinates in a horizontal plane - (x,y)
T(x,y,d,t_{i}) temperature versus depth (d = depth) at time t_{i}, i \in [1,n] , along the vertical V_{x,y};



  1. Go to the "Designer Graphics" and select the type of "well" chart (cm. Drawing 2).
