Question
Which method of analysis is used for insulating glass?Answer
If there is an insulated glass unit selected for the design in RF‑GLASS, the method of the large deformation analysis is set by default. Based on the existing gas volume in the space between glass panes, this method of analysis is also required and cannot be changed.

Displaying Temporary Analysis Models from RF-GLASS
When using the RF‑GLASS add‑on module, you can define in the main program just the geometry as well as the load situation of the structural component to be designed. The respective support conditions and all further design-relevant definitions, for example the layer structure and support conditions, can be further specified in RF‑GLASS.

Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
- Which stresses are most important for glass design consideration when using RF-GLASS?
- I would like to design a glass pane with temperature loads. In this case, a message appears saying that the load case includes the "temperature" surface loads types that are not transferred to the created temporary model. How can I consider the temperature loads?
- Is it possible to design a spherically curved glass pane in RF‑GLASS?
- Are there any programs or add-on modules specially developed for glass structures?
- Which method of analysis is used for insulating glass?
- Is it possible to design insulating glass using the RF-GLASS add-on module?
- Does the activation of the partial safety factor GammaM have an effect on the calculation in RF‑GLASS?
- Is it possible to display the loads of the secondary seal of an insulating glass pane?
- When calculating a glass pane with RFEM, no stresses are displayed. Is there an error?
- Where can I find the details of a layer composition in the RF‑GLASS add-on module?
