This section explains how to obtain the IR analysis of a sphere-shaped structure.
Step 1. The first step consists of creating a new data file where all the parameters of the simulation will be saved. Use the command ‘New’ from the File menu. Select IR type.
Selection Method dialog box
Step 2. The second step is to generate the sphere. Select Geometry → Solid → Sphere. It will be located at (0,0,2) and the radius will be 2 m.
Step 3. The next step is to assign a material to the geometry model. Select Material → Assign Material and assign "Aluminum" to the surfaces of the sphere.
Assign material to the geometry model
At this point it is possible to visualize the materials assigned by clicking on the Material View icon in the toolbar.

Step 4. Configure the Environmental Parameters. Use the Environment → Parameters option to configure the environment.
This option will open a new panel where it will be possible to configure different features of the environment, such as the atmosphere, wind, sun position, sea, geographical position and trajectory, and the transmittance of the atmosphere.
In this example we will leave all the default parameters except the convergence options and the transmittance calculation.

Step 5. Meshing the geometry model. Use Meshing → Create and visualize mesh option to create the mesh.
Configure the meshing parameters: divisions per meter on planar and curved surfaces, duplicate normal vectors on open surfaces and number of processors. Then click "OK".
Step 6. Execute the simulation. Use Calculate → Execute to perform the thermal analysis.
Select the number of processors to be used and click on "OK".
Step 7. Show Simulation results.
- Thermal Analysis: Use the Show Results → Thermal Analysis option to display the thermal analysis results.
Thermal Analysis view
- Radiance Analysis: Use the Show Results → Radiance option to display the radiance results.
This view displays some information about the radiance results and allows to configure the same settings as the thermal vision view. The main difference is the information shown in the window when clicking on the image while pressing the Ctrl key.
