WINISO®
Imported CAD files can be prepared by automatic detection and correction of CAD errors. Thus, complicated components and systems can be analysed and calculated with short computing times and small data sizes. The integrated FEM calculation kernel enables the most accurate results.
Features
- Highly automated geometry preparation of CAD data (.dxf & .dwg)
- Detailed transfer of CAD data incl. radii and bevels
- New solver and new calculation core with automatic FEM meshing
- Automatic FEM meshing can be controlled flexibly and specifically, resulting in high calculation speeds
- Calculation according to the "radiosity model" (new cavity model according to EN ISO 10077-2:2018) and with equivalent conductivity (EN ISO 10077-2:2012/2018)
- Simple definition of foils, coatings and surface properties using line drawings
- Automatic material allocation based on CAD layers
- Gas filling for inter-pane spaces according to DIN EN 673 freely mixable
- Automated Uf calculation of window and façade profiles

CAD import
CAD import and clean up
WINISO® imports CAD data as DWG, DXF and STEP. Efficient tools for CAD preparation create a seamless transition from CAD to FEM during data transfer.
Polygons
During the generation and processing of the polygons, the essential features and contours of the design are obtained and the foundation is laid for efficient and fast FEM calculation.
Polygon Search Flood Fill
The Flood Fill polygon recognition gives the user an intuitive, powerful and robust tool for preparing even problematic CAD data.
Clean joints
The joint clean-up automatically corrects offset errors from the CAD data and removes incidental details. The result is a coherent design that focuses on the essentials for the FEM calculation.
Tools – Part 1
With an extensive CAD tool set, the imported CAD data can be easily and flexibly reworked and supplemented
Tools – Part 2
With an extensive CAD tool set, the imported CAD data can be easily and flexibly reworked and supplemented
Project processing
Surface machining
Surfaces reflect the geometry in the WINISO® FEM model. The structure of the simulation project is completely defined in just a few steps.
Material assignment
Automatic assignment of materials to layers and automatic detection of profile cavities and boundary condition surfaces for a speedy and error-resistant model definition
Boundary condition
With the automatic detection of cavities and the flexible definition of boundary conditions and surface properties, almost any problem can be modelled quickly and precisely.
Cavities
The definitions of frame cavities and spaces between panes from a wide range of standardisation are implemented in WINISO®: DIN EN ISO 10077-2, EN 673, DIN EN ISO 6946, ISO 15099.
Frame according to EN ISO 10077-2
WINISO® implements both calculation methods for window profiles with cavities provided for in DIN EN ISO 10077-2 in accordance with the standard: the equivalent conductivity method and the radiosity method introduced in 2017. Automatic checks ensure a consistent and standard-compliant calculation approach in all details.
ISO 15099
WINISO® enables the calculation of window profiles and glazing according to the specifications of ANSI/NFRC-100 and ISO 15099 according to the requirements of the US standardisation for the international market
