Thermal analysis
Simulation of heat conductivity
Steady and transient heat transfer process are simulated in the VISOR-SAPR environment.
On the Thermal Analysis tab it is possible to generate the FE model, edit, define thermophysical parameters to finite elements of heat conductivity (thermal conductivity coefficient, heat absorption coefficient, unit weight) and convection (coefficient of convective heat transfer), define boundary conditions, define standard and non-standard types of loads, carry out analysis, evaluate and prepare documentation with the output data for thermal analysis. The Thermal Analysis tab becomes available when you generate the problem with model type 15.
Thermal Analysis tab ' to generate, modify, analyse and evaluate problems with heat conductivity
- The steady heat transfer analysis and transient heat transfer analysis may be carried out for the whole model and for certain nodes and elements.
- Thermal analysis may be carried out both in 2D and in 3D statement.
Finite elements of heat conductivity and convection
Unidimensional, 2D and 3D finite elements of heat transfer are used for problems with heat conductivity. To simulate the contact between the surface and environment, there are special finite elements of convective heat transfer.
Finite elements applied to carry out thermal analysis
All finite elements of heat conductivity were verified for the convergence of the solution with analytical methods.
Types of thermal load
To simulate different types of thermal load, the following data may be applied: specified temperature at node, heat flow at the body surface, specified exterior temperature for the elements of convection, non-standard types of loads and radiant heat transfer (radiation).
Heat flow in nodes of design model
It is possible to compute the heat flow in problems of heat conductivity and to sum up the heat flow for the selected load cases.
Generation of thermal loads by results of thermal analysis
To create thermal loads to compute the stress-strain state of the structure, it is possible to use the following results:
- in problem with steady heat transfer ' computed thermal fields in any load case;
- in problem with transient heat transfer ' analysis results at any time.
Generation of thermal loads on elements of design model according to computed temperatures

Preview, evaluation of analysis results, documentation
The output data of heat transfer analysis may be presented in tabular and graphical form: as mosaic plots and contour plots for temperature, mosaic plots of heat flow. The input data as well as output data may be documented with the help of Report Book.
Input & output data is displayed in graphical and tabular formats
In this system the user could simulate different types of heat transfer (heat conductivity, convective-radiant heat transfer). It will be helpful when you solve the problems like thermal analysis of the building envelope, design effective fire protection for building structures, determine real fire resistance limit, etc.
