To access the global settings of the stress-strain analysis, use the shortcut menu of the navigator entry or click the button
in the table toolbar for the stress-strain analysis. This chapter describes the parameters available in the Global Settings dialog box.
Tip
Use the
at the bottom of the dialog box, you can restore the default settings.
Calculate Stresses
By default, the stresses are displayed in the FE mesh points ('In mesh node'). Alternatively, it is possible to display the results in user-defined points of the grid ('On grid point'), which are defined in RFEM in the properties of surfaces and solids.
Smoothing Settings
The options for smoothing results are described in Chapter Result Smoothing of the RFEM manual.
Analysis Method
This section controls how the design internal forces of the load and result combinations are transferred to the design. Three design methods are available for selection in the list.
- In the enumeration method, all load and result combinations of a design situation are calculated individually. This usually leads to the most accurate results, but may also lead to increased calculation time.
- In the Envelope Method , the enveloping internal forces of all load and result combinations of a design situation are first calculated, and then the designs are performed. This usually leads to shorter calculation times compared to the enumeration method.
- For the Mixed Method , you can define an upper limit for the number of load and result combinations of a design situation to be designed according to the enumeration method. If the number of combinations exceeds this limit, the design is carried out with the enveloping method.
Optimization - Maximum Allowable Design Ratio
The add-on provides the option to optimize standardized cross-sections (see also Section Sections) and surface thicknesses (see also Section Thicknesses). When checking the possible variants, the utilization of a variant is compared with the maximum value defined here.
Storing Results
The result files can become very large for large models with several thousand objects if all results are saved in them. Depending on the selected setting, a result is saved for each location, stress or grid point, or object. Thus, you can influence the file size accordingly. Notwithstanding the above, you can display all results in the program, since the missing results are recalculated automatically.
Strains
If you select the 'Strain analysis' check box, the program performs an analysis of surface strains in addition to the stress analysis.
