for thermal analysis of WINDOWS & DOORS

a child’s play

Follow the interactive Tour (legth: 7 minutes) Look how it is easy to make a simulation with the new Frame Simulator 2. You will be guided through a complete calculation of the thermal transmittance Uf for a window’s frame node and the PSI linear transmittance for a glazing spacer. At the end of the Tour you will be able to download the project and open it with our free Frame Simulator Viewer.

Do you want the truth? Frame Simulator PRO is a very powerful software that that makes calculation of the thermal transmittance in windows and doors an extremely easy process. If you really want to know how the heat is flowing through a window, a lift&slide, a shutter box or an external door now you can do it yourself, in few minutes. download here a free viewer with sample projects

In few simple steps you will be able to see how the heat flows through your windows, to predict condensation problems, to discover weak points in your frames, to obtain the thermal transmittance parameters (U-values) for frames and glazing and… much more! It has been designed to make just what you need: to calculate thermal performances of windows and doors. No useless or complicated things. That’s why it is so effective and easy to use. To obtain the same results with other software you should invest more time, more money, more expertise.

Projects created with other software can be imported in dxf format. Need of retouching and adjusting lines is minimized thanks to a sophisticated algorithm that optimizes the imported files. Import process is therefore painless. New drawings can be created and modified in the program with the use of simple but effective tools.
With the Frame Composer optional module you can calculate the thermal transmittance of entire complex fenestration (glazed area+frame) or opaque panels.
With Frame Simulator PRO you will own a professional tool, that allows you to make calculations on windows and doors with all the precision required by the ISO 10077 norms, but without investing a fortune. With it you can run many analysis in a very short time and thus increase the productivity of your business.

Calculation

Frame Simulator is powerful and extremely accurate in calculation.
Precise simulation of the heat transfer is performed using two-dimensional numerical method conforming to ISO 10077-2 (finite elements). Computation time is highly reduced through an optimized triangulation routine.
Frame Simulator helps in implementing EN ISO 10077-1 and EN ISO 10077-2 because it automatically adopts all the parameters and the calculation criteria written in the norms.
With Frame Simulator PRO you can calculate the thermal transmittance (Uf) and the linear conductance (Lf2d) of any type of window frame. You can also see how heat flows at any point in the frame section and examine the critical points of heat loss.
The program calculates the dew point for the internal ambient and it shows the areas where there is likely to be surface condensation on the window.
With the Frame Composer module you can calculate the Uw thermal transmittance of entire complex fenestration (glazed area+frame) or opaque panels, based on the Uf values obtained from the Frame Simulator module. Calculation is made according to ISO 10077-1 on rectangular windows, taking in consideration the additional thermal resistance of any existing shutters or curtains. Frame Composer can also be used to calculate the Ug thermal transmittance of the glazing, based on the glass panes and filling gas composition.
The data results and colorful output diagrams can be very effective for publishing in test reports, offers and commercial documentation.

Output

Calculation results are available as data values and colorful diagrams.
THERMAL QUANTITIES
Frame Simulator allows to calculate thermal quantities as defined by European standards:

• Uf Frame thermal transmittance in W/(m2K)
• Ug Glazing thermal transmittance in W/(m2K) – with Frame Composer module
• Uw Window thermal transmittance in W/(m2K)
• Lf2d Linear thermal conduttance in W/(mK)
• Heat flow rate density in W/m2
• Dew point temperature in °C

COLOR GRADIENT DISPLAY

• Temperature: data value and color gradient at any point in the section
• Isotherm: number of lines can be freely set
• Flow: heat flow rate value and color gradient at any point in the section
• Flow Pattern: color gradient lines with heat flow direction
• Edge: thermal resistance values of internal/external borders
• Areas: thermal conductivity of the areas, according to the norm interpretation, in color pattern and value
• Triangulation mesh: display of the triangulation mesh used for the calculation (black/white)
• Condensation: dew-point, isotherm and areas where condensation can occur on internal window surface

Content

PRO version is full-optional and can be used for the analysis of complex sections, which can be automatically imported from external drawings via .dxf files.
This version includes two separate program modules:
Frame Simulator module: for the thermal analysis of frame sections and calculation of the frame thermal transmittance (Uf).
Frame Composer module: for the calculation of the thermal transmittance value for glazing (Ug) and windows (Uw).
