In RFEM, surfaces are automatically connected if they have common boundary lines. If the definition line of a surface is lying in another surface, the line is automatically integrated into the surface, provided that it is a planar surface. For quadrangle surfaces, however, automatic object detection would be relatively time-consuming. For this reason, the corresponding function is deactivated. The integrated objects must be specified manually.
If you want to model two intersecting surfaces, RFEM offers you the possibility to create the section line automatically. In the program, this function is referred to as intersection. When generating an intersection, the modeled surface is split into components. This has the advantage that the components can be taken into account in the determination of the internal forces, or deactivated.
If nonlinear effects - such as failing supports, foundations, member nonlinearities, or contact solids - are used in the model, you can deactivate them in the global calculation parameters.
If intersections created in RFEM 4 are opened in an RFEM 5 file, the file management of intersections remains in the old format for compatibility reasons. Thus, the individual partial surfaces of the intersection can be activated or deactivated using only the "Integrated/Components" tab, all partial surfaces can only have the same thickness, and it is impossible to use the separate FE mesh refinement for the individual surface components.
In RFEM and RSTAB, you can import background layers from a DXF file. If the main nodes of the model have already been set, it can be useful to deactivate the snap mode of the background layer.
The Time Course Monitor displays the results of a time history analysis from RF‑/DYNAM Pro – Forced Vibrations. The graphic can be adjusted in the settings. This can be reached by right-clicking in the shortcut menu. For example, you can activate or deactivate the grid in the graphic. Those changes are overtaken into the printout report when you print the graphic.
The result window of the cross-section properties can be adjusted individually using the [Filter] button in the table menu bar. You can then activate or deactivate the individual cross-section parameters in the dialog box.
In order to also consider loading when copying, mirroring, or rotating, the corresponding option must be activated. To do this, select the corresponding check box in the "Detail Settings for Move/Rotate/Mirror" dialog box. Then, loading is included when copying until you deactivate this function.
