Thermal analysis of windows according to UNI EN ISO 10077-2: 2018
Frame Simulator is a professional tool that allows you to perform a complete thermal analysis of a window or curtain walling module in a short time.

The program is very easy to install and can be used even if you don’t have great computer or thermal skills. In Frame Simulator you can import drawings in DXF format and it takes a few minutes to pass from the drawing to the final result. The thermal calculation is fast and the results are immediately interpretable with highly effective and realistic images and graphics.

In addition to obtaining the Uf transmittance value and the PSI linear transmittance value of the spacer, with Frame Simulator it is possible to see the trend of the heat flow at each point of the section and identify the most critical areas where to intervene.
The program also clearly indicates the possibility of condensation on the internal surfaces of the frame.

With the Frame Composer module, supplied with the program, it is possible to calculate the thermal transmittance Uw and Ucw of complete windows and doors (frames + glazing) and curtain walls, from simple single-sash windows to complex combinations with many doors, with internal and roller blinds or external taxes. It is also possible to evaluate the contribution of thermal resistance given by the blinds.

Two calculation modules are included in the program:

  • Frame Simulator for the finite element analysis according to UNI EN ISO 10077-2: 2018 of the frame (Uf, Ψ) and bins (Ursb) and for the calculation of curtain walls (UTj, ΨTj) according to ISO 12631: 2017
  • Frame Composer for calculating the Uw transmittance of the entire window or Ucw of the curtain wall, the UG of the glass and the additional resistance of the blinds

The program is validated according to the new UNI EN ISO 10077-2: 2018 standard (calculation of thermal transmittance – numerical method for frames).

Perpetual License Updates
12 months of free updates are provided with the purchase of a new perpetual license.
Upon expiry it will be possible to subscribe to an Updates subscription for another 12 months, thanks to which you will have access to any updates released during the period for your license. The fee for the Updates subscription varies according to the license held.
If after the first 12 months the Updates subscription is not subscribed, it will be possible to continue using the non-updated program and possibly purchase the upgrade to an updated version separately.
The Updates subscription will also grant access to additional confidential documentation.

Perpetual License Upgrades with subscription redemption
In case of purchase of a Perpetual License with redemption of a License subscription in version 6 or later, 12 months of free updates are provided starting from the subscription start date. Upon expiry it will be possible to subscribe to an Updates subscription for another 12 months.


When purchasing the software, you can choose between three different activation methods: with Software Key or with USB Key or with Web License.
To use the program simultaneously on multiple computers you need multiple licenses or multiple subscriptions.

Activation with SOFTWARE KEY

Standard activation method, included in the program price.
The program is activated by an alphanumeric activation key, valid for the computer on which it was initially installed.
The activation key is generated and sent within a few hours of payment, based on a code (Computer code) shown during installation, which the user must send us.
Once the license has been activated on a computer, it is always possible to transport it to another machine: by means of a procedure via the internet, it is possible to deactivate the license on the current computer and activate it on another computer.
For a possible reinstallation of the software on the same hardware, the initial procedure is repeated, by entering the same software activation key.
If, on the other hand, the hard disk has been reformatted or all or part of the hardware has been changed, we will provide a spare installation key upon request (this can only be done once).

Activation with USB HARDWARE KEY

Optional activation method – to be purchased separately.
If you choose this mode, the user will receive by registered mail or courier a USB key with all the licenses purchased (one of each type).
Activation instructions will be provided with a separate email, in order to use the programs on any computer (not simultaneously) simply by moving the key from one computer to another.

Activation with WEB LICENSE

Flexible access for smart working with an annual subscription.
Web License allows you to access your licenses anywhere and at any time by entering only your username and password.
This simplified access mode is particularly suitable for work teams that need to share the use of programs remotely.
Any member of the group can start the software by simply entering the username and password provided.
It is also possible to use the software simultaneously based on the number of simultaneities purchased. To use Web License you must already have a license in version 5 or higher.

How to order
Choose from the options shown above and click on “Add to cart”. If you have chosen the activation with a new USB key return to catalog and add a USB key to your order.
Proceed to checkout and fill in all the fields for billing purposes. If you are not already registered, please enter your user name and password. Login is required to download the installation files.
