– psi contributions separation when using three boundary conditions;
– various bug fixes.

We’ve just released update 3.0.2 for Mold Simulator and Frame Simulator, our thermal bridge analysis and window transmittance computation softwares. Please go to their respective pages to get the latest viewer version.

Thermal Bridge

Thanks to U-factors feature of Mold Simulator 3, it is possible to compute the contribution of every room to global psi value of a thermal bridge. In this tutorial we’ll refer to file example13.mos contained in Mold Simulator’s documentation folder.
Suppose you’ve a T type of thermal bridge:

Thermal Bridge
It is very important to create two different section elements (“Top element” and “Bottom element”) to get correct results.
We want to use four different boundary conditions for the internal environments; for this reason you must pay particular attention to boundaries setup.
1- Every internal boundary must have the same temperature;
2- Grouping must be by temperature, but you must disable “Just connected boundaries” option;
3- A separate U-factor surface must be associated to each boundary;
4- U-factors of room A must be grouped under “Room A” U-factors group (same for U-factors of room B).

Thermal Bridge
Now you’re ready to get separate linear thermal transmittance contributions of this thermal bridge simply passing to simulation tab.

Thermal Bridge

In many thermal bridge computations, you can choose the reference point against which to calculate the linear thermal transmittance (psi). The most common example is the edge of a building:
Thermal Bridge
It is possible to calculate psi compared to the internal reference point (lengths A and B) or outside (C and D). Thanks to Mold Simulator 3’s new features, you can do both with a single project following these simple steps:
1- plot the section elements to identify lengths C and D of the thermal bridge:

Thermal Bridge
2- change the properties of the newly created items by enabling the “double-length” option. Some new lines will appear for each item;
3- adapt to the new lines in order to identify the lengths A and B:

Thermal Bridge
Turning to “Simulation” tab, you will notice two distinct values of thermal bridge’s linear thermal transmittance (psi): one refers to the internal reference point and the other one to the outside point. For more information, please go to Mold Simulator page.

Frame Simulator is our flagship software for window transmittance (EN ISO 10077-2) computation. After two years of development, we’re pleased to announce Frame Simulator 3; for more information please go to Frame Simulator page.

After two years from the release of Mold Simulator 2, we’re extremely pleased to announce Mold Simulator 3. Aside the huge list of improvements and new features, we’ve added a new version of the software: Mold PSI!, specifically designed for linear thermal transmittance computation. For more information please go to Mold Simulator page.

We’re pleased to announce the release of update 2.1.7 for both Frame Simulator, our window transmittance simulator, and Mold Simulator, our thermal bridge software. This is a maintainance release, with a some bug fixes. You can get the latest viewer versions here:
Frame Simulator | Windows Transmittance
