AREE
"Areas" tab lets you specify the type of material composing every part of the frame, choosing its type and relative properties. Available commands are the following:
|
Fill area with the properties of a material. To assign a material you need to click in the middle of the desired area on the viewport. |
|
Remove the properties of a material from an area. |
|
Remove all materials from project. |
|
Remove the properties of a material from a segment. |
|
Modify the properties of an area. Simply click on an area, modify its properties and press "Ok" button. If "Apply to materials with same name" is checked, changes will be applied to every material with this name; the same applies to "Apply to materials with the same color or texture". If "Apply thickness to all materials is checked, current material's thikness will be set to every project's material. |

Read the properties of a material clicking on an area. |
Material types
standard: it's the material composing the main structure of frames, for example the wood of a window or the glass of a window. You can specify its conducibility and emissivity;
segment: it is possible to assign properties to segments as well. For example, suppose you have a cavity with reduced emissivity: now you just have to assign this material, with the proper emissivity, to its border (see tutorials page for an example). It is also possible to assign a U-factor surface to every segment: please refer to U-factors documentation for more information;
adiabatic: material that prevents heat to flow. It is used at frame's extremities to get a correct simulation. See tutorials page for an example;
10077-2 insulation: to get the correct frame's transmittance computation you have to replace glazing or panel with an insulation panel. See tutorials page for an example;
cavity: you can manually create cavities by filling areas with this material type;
gas: to be used, for example, as filling for glazing's gaps; it MUST NOT be used to fill cavities. See tutorials page for an example;
transparent: you have to use it in areas that don't exchange heat with the frame; it's useful to obstruct open cavities. See tutorials page for an example;
13947 Screw: this material has been added in version 2.0. It's behaviour satisfies 13947 standard.
Material properties
Materials can have several properties, depending on their type. Here you are a complete list of material properties:
name: material's name;
conductivity: thermal conductivity. It can be anisotropic and can be computed from resistance-thickness values by clicking the "R" button on the right;
emissivity: thermal emissivity, interacting with cavities equivalent conductivity. This parameter can be assigned to areas and segments; when a segment has an assigned emissivity, the area's one is ignored;
color: color displayed in the viewport;
texture: sit is possible to use images on materials, adding visual appeal to your projects. Clicking on the button you'll open the image library window: see image library documentation for more information. The value on the right controls image's scale;
opacity: controls material's transparency;
3D height: areas and segments can have a thickness, giving 3D appearence to your projects;
cavity type: type of a cavity material;
volumetric mass: volumetric mass of a gas material;
dynamic viscosity: dynamic viscosity of a gas material;
conductivity: conductivity of a gas material;
specific thermal capacity: specific thermal capacity of a gas material;
Eq. conductivity: equivalent conductivity. See EN 13947 standard for more informations about screws' equivalent conductivity;
Vapour diffusion (μ): vapour diffusion, used for interstitial condensation tests;
Layer thickness: when using segment materials representing vapour barrier it is necessary to specify thickness as well.
Material library
Materials can be stored and managed with a new powerful library tool; see material library documentation for more information.
Cavity
Detection
Mold
Simulator can automatically detect cavities. These are the parameters
that control this functionality:
UNI EN ISO 6946
unventilated slit size: the cavity in contact with the outside through with larger slits will be ignored;
unventilated color: color of the material used for non-ventilated cavities;
cavity material thickness: thickness of the material used for the cavities;
skip larger than 300mm: cavities with dimension greater than 300mm (along the direction of heat flow) are ignored;
skip larger than 500mm: cavities with dimension greater than 500mm (along the direction of heat flow) will be ignored.
UNI EN ISO 10077-2 (available only if you have a Frame Simulator license)
unventilated slit size: cavities with smaller slits are considered as unventilated;
partially ventilated slit size: cavities with smaller slits will be considered as partially ventilated;
unventilated color: color of the material used for non-ventilated cavities;
partially ventilated color: color of the material used for partially ventilated cavities;
cavity material thickness: thickness of material used for the cavities.
UNI EN ISO 10077-2 - not ventilated algorithm applies UNI EN ISO 10077-2 skipping partially ventilated cavities.
ISO 15099
unventilated color: color of the material used for non-ventilated cavities;
partially ventilated color: color of the material used for partially ventilated cavities;
cavity material thickness: thickness of material used for the cavities;
jamb height: the height of the jamb.
