In the Result Diagrams dialog box, it is possible to create average regions to prepare the results for engineering. This function is available with the 'Edit Average Regions' button. The dialog box in Figure 1 opens.
Define the average regions in the table columns on the left; entries for Start, End, and Length are interdependent. Each region can be activated separately. The 'Use for Results' section controls for which deformations, internal forces, stresses, or strains a smoothing is to be performed. The smoothing can be constant or linear for all average regions.
Furthermore, an average line can be displayed over the entire result diagram via the button of the same name (Figure 2).
The integral of the average region is displayed if the 'With Result Interpretations' checkbox is selected in the settings of the result diagrams (Figure 3).
In the 'Global Calculation Parameters', there is the setting 'Number of Member Divisions for Result Diagrams'.By default, this value is preset to '10'.If members with very different lengths are used in a model, it may happen that the preset value of '10' is too small. This is then reflected, for example, by the fact that the parabolic moment diagram is not displayed correctly for the shorter members.To avoid this problem, enter a higher value, e.g. '50'.Thus, a parabolic moment diagram is also displayed on the shorter members.The length of the sections results from the length of the longest member in the structure divided by the defined number of member divisions. The finer division of members applies to all members of the model.
If the beam and the surface share the same plane, they are firmly connected to each other.
Although the member end has a member end hinge, it is already rigidly connected to the surface in the next FE element and shares the load transfer with the surface by means of bending. To avoid restraining moments, the surface must also have a line hinge.
AnswerA section can run through a complete structure and display the results on intersected surfaces. It is important to define which surfaces are intended for displaying the results of the section. Figure 01 shows a section defined in such a way that all intersected surfaces (default setting) are displayed. In this case, both walls will also be intersected and the results will be attached to the result diagram (see also Figure 02).If you want to only display the section on certain surfaces, define the required surfaces in the "Edit Section" dialog box (see Figure 03). The section is then displayed in the result diagram as requested (see Figure 04).
AnswerThere are several possibilities to evaluate the results of line hinges:
- Graphical evaluation of the results: Under "Releases" in the Results navigator, you can display various forces and deformations of the line releases in the graphic.
- Display of the results in tables: For the tabular evaluation of the results, Table "4.45 Line Hinges - Deformations" and Table "4.46 Line Hinges - Forces" are available.
- Evaluation by means of result diagrams: You can use the shortcut menu to view the result diagram of the line hinges.
The result diagram of a line release (Figure 1) or a line hinge (Figure 2) can be displayed by right-clicking the relevant line release or line hinge. From the shortcut menu, select the "Result Diagrams" entry.
The video shows how the results of a line release/a line hinge can be displayed in the work window and in the "Result Diagrams" dialog box.
AnswerAdditional information is available in the work window for each line support. They are interpreted as follows:𝛴 : sum as resultant forceΦ: average valuex: distance of line's midpoint from the line starte: eccentricity of the resultant with respect to the line's midpointM: moment due to the eccentricity of the resultant
In the settings for the result diagrams, you can also change fonts and colors.
First, open the result diagram of a member, line support, section or line. Then select the desired internal forces and deformations.
Finally, right-click the navigator and select Save Check Boxes State.
Use Refresh Check Boxes State (this button is now available) to cancel your settings.
By default, only two values (max and min) are displayed on the result diagram of line supports.
But you can also display all values by using the settings in the "Display" navigator:
"Results" --> "Support Reactions" --> "Actual" --> "All Values"
The division depends on the FE mesh: A value is displayed on each FE node.
In this way, you can influence the division, for example by a FE mesh refinement on particular surfaces or lines. In contrast, the numerical output in the result table, and thus in the printout report, is controlled only by the global FE mesh.

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
