With this package you can perform DYNAMIC thermal analysis of any construction element, windows frames and building structures, in compliance with the relevant norms.

Thermal analysis of the window/wall installation joint

The installation joint of a frame is a border zone between two standards: EN ISO 10077-2 for window and EN 10211 for walls. The two norms provide different methods for the calculation of cavities and assignment of the surface resistances. Additionally, for a precise calculation of the linear transmittance Ψ of the thermal bridge between the frame and the building structure, it is necessary to know the actual Uf transmittance of the frame and Ug of glass.

With Building&Frames package you will be able to perform calculation of frames within Mold Dynamic. When calculating a window/wall joint it will be therefore possible:

• to calculate cavities in wall according to ISO 6946 and cavities in frame according to ISO 1077-2
• to automatically apply an increased surface resistance on the internal frame border, as required by ISO 10077-2
• to use the library and the calculation functions of the glazing to obtain accurate Ug values and surface temperatures on the glass/frame border

MOLD SIMULATOR DYNAMIC – v.5

In addition to the steady-state analysis, MOLD DYNAMIC can also perform 2D/3D transient fem simulations with time-variable input parameters. You can assign to the boundaries time-based curves of temperature, humidity and heat flux (for example, the solar radiation on a wall or the heat flow in a radiant system). Curves can be created with the tools of the program or imported from tabular data, such as climate data files.

Mold DYNAMIC performs a series of finite element analysis of the structure using successive points on the curves of the boundary conditions and taking into account the results of previous simulations. In this way you can obtain the actual trend over time of the heat flow and temperature at each point of the structure.

Mold DYNAMIC automatically calculates all the dynamic characteristics of the complete structure according to UNI EN ISO 13786 such as heat transfer matrix Z, phase shift, attenuation, heat capacity per unit area, admittance and dynamic thermal transmittance.

It is important to note that these values ​​are detected on the actual structure under consideration and therefore also for complex building components including thermal bridges, not only for packets of homogeneous layers as normally considered.

VALIDATION
The program is valid according to the UNI EN ISO 10211:2018 – Thermal bridges in building construction – Heat flows and surface temperatures – Detailed calculations.
 

FRAME SIMULATOR – V.5

Frame Simulator PRO is a professional tool that allows you to perform complete thermal analysis of windows and curtain walling modules according to the ISO 10077-2:2017 and ISO15099:2003.
It really takes only few minutes to go from your cad drawing, that you can import in the program, to the modelling output. The thermal calculation process is performed in respect of the norm requirements and results are immediately interpretable, thanks to images and graphics of great realism.

In addition to obtaining the Uf thermal transmittance value and the PSI linear transmittance of the spacer, with Frame Simulator is possible to see the the heat flow at each point in the section and to identify the most critical areas requiring improvements.
The program also indicates the condensation risk on the internal frame surface.

With Frame Composer module, supplied with the program, you can calculate the thermal transmittance Uw for complete windows (frame + glazing), from a simple one-sash window to complex fenestrations with multiple sashes. You can even evaluate the contribution of thermal resistance given by curtains and shutters.
