Our Psi-Therm software is the leading Finite Element Mesh analysis tool available for the analysis of thermal bridges in construction components. This powerful design tool is validated to ISO 10211, with automatic mesh generation in order to ensure accurate results in accordance with the applicable standards. Exclusively available to Passivate customers, the software now comes with a boundary condition database for analysis according to BR497 and Passive House conventions. Saving you the need for complicated spreadsheets and numerous external calculations, the software produces U-values, Psi-values and Frsi-values, producing a comprehensive report in accordance with the requirements of the international standards.

CALCULATION METHODS
The finite element mesh calculation is performed in accordance with EN ISO 10211. Boundary conditions according to BR497 and Passive House are available in the boundary condition tables. Both the Psi-value and Frsi values are determined automatically following the analysis.
CALCULATION
To ensure your analysis is performed in strict accordance with ISO 10211, the software automatically generates and refines the mesh size in order to meet the convergence criteria. This also limits processing time required by not over-complicating the mesh.
INPUT OPTIONS
The Psi-Therm software uses a CAD platform, meaning the user benefits from advanced drafting tools to generate thermal bridge models quickly and easily, as well as being able to import .dwg and .dxf files of any AutoCAD release version.
Some drafting tools include;
- Guides / auxiliary path
- Editing (lines, …)
- DXF / DWG import
DISPLAY OPTIONS

PRINT REPORT
The report can be output to many formats including PDF, JPEG, direct to printer and many more. The comprehensive report satisfies all the requirements of ISO 10211 & BR497. Alternatively, the printed content can be limited to the input data, materials listings or the mathematical calculation depending on the user requirements. The print layout can be edited by the user to display only selected images of the model, as well as integrating your own corporate logo into the printed report.
EDITING TOOLS
Many editing tools are available for the adjustment of the construction model. Components can be selected, moved, re-sized or re-shaped individually or as blocks, making the editing process quick and simple. Individual points on polygons or boundary conditions can be moved at the click of an icon and easily snapped to neighbouring polygons!
