Cavities

,
Description

In this dialog window you can define the properties of air cavities according to EN ISO 10077-2. The use of the wizard is explained in detail in tutorial 4.

Version

Selection of the standard version for the computational algorithms used for the calculation of the equivalent conductivities resp.  the energy transport for cavities.

Calculate emissivities

Emissivities (long-wave radiation properties) in the main heat flux direction according to EN ISO 10077-2 should be calculated as average based on the set radiation surface properties by flixo.

If this option is not activated, the average emissivities have to be defined in the cavity materials.

Anisotropic conductivities

If this option is selekted, then per cavity in both x and y direction an equivalent conductivity according to EN ISO 10077-2 will be calculated and applied.

Automatic division

Determines whether air cavities should be divided according to 10077-2 into smaller air cavities:

Division of air cavities can have a significant influence on the results of the calculation. According to the standard, only air cavities with outlets smaller than 2mm are allowed to be subdivided into smaller air cavities.

Ignore existing colors

Determines whether manually defined, visible boundaries of air cavities to other air cavities with the same properties should be ignored or taken into account in the division calculation.

Division of air cavities can have a significant influence on the results of the calculation. According to the standard, only air cavities with outlets smaller than 2mm are allowed to be subdivided into smaller air cavities.

Marker color

Color with which additional division points should be highlighted.
