RF-GLASS | Calculation
The global calculation assigns the stiffness determined by means of the selected composition and the glass geometry to each surface. Then, the calculation proceeds using the plate theory. It is possible to select whether the shear coupling of layers should be considered.
In the case of the local calculation, you can further specify 2D or 3D calculation. The 2D calculation means that single layer or laminated glass is modeled as a surface and the calculation of its thickness (using the plate theory) is based on the selected composition and glass geometry. Similarly to the global calculation, you can optionally consider shear coupling of layers.
The 3D calculation uses solids in the model to substitute each composition layer. In this way, results are more accurate but the calculation may take more time.
It is possible to model insulating glass only if local calculation is selected. The gas layer is always modeled as a solid element, so it is necessary to design individual insulation glasses separately from the surrounding structure. The calculation applies the ideal gas law (thermal equation of state of ideal gases) and the large deformation analysis.
