Defining the Construction

You can enter the geometry of the construction either directly in flixo or you can import it from CAD products and complete it on the model page afterwards.

To enter the construction, use the tools and objects on the Model page. You can switch to the Model page by clicking on the corresponding tab just below the work area


With the following tools existing objects can be edited:

Select, Move, Scale



Assign Properties



Measure Distance


With the following tools new objects can be created:

Rectangular Domain

Elliptical Domain

Polygon Domain

Air Cavity EN ISO 10077-2, ,

Boundary Condition

Heat Source,


The geometry of the construction can also directly be imported from CAD products and adjusted in the model page.

Functions like logical operations, Align object, the use of guidelines and grids facilitate the data entry. If the construction is more complex and is entered on multiple layers or if it needs to be defined with previously designed elements, it would best you get to know the Layers flyout and Component flyout before hand.

For a complete definition of the construction, you must enter the materials and boundary conditions. The materials assignment can be done with the Assign Properties tool or with the Boundary Condition tool. Alternatively, materials and boundary conditions can be assigned by dragging them from the materials database or table, or respectively from the boundary conditions database or table.

Models can also be created automatically on the basis of other models using custom rules. If the source model is changed all derived models are updated automatically. The following rules are supported:

Exchange of materials

Exchange of boundary conditions

Exchange of parameters

Exchange of glass unit properties

Calculation of vapor diffusion according to Glaser


A step-by-step explanation of these techniques can be found in lesson 1 and lesson 2, and the import of CAD product constructions can be found in lesson 3.
