The described effect is not a display error, but only a question of perspective and a good example of an optical illusion. It depends on whether you perceive the representation of the axis system as an inner or outer corner.
Example: Rubik's Cube in Isometric View
The yellow side of the cube is the top surface. In the preset isometric view, you can see the inner corner of the coordinate system diagonally from above. If you simply turn the view upside down, so that Z points upwards, X to the right, and Y to the left, you can look at the bottom side of the cube, that is from above on the lower outer corner of the coordinate system.
If you rotate the view by 45 ° about the horizontal axis, you may get the impression that you look at the inner corner of the coordinate system. However, this is the outer corner.
The program provides the "Min/Max Values" option under the "Scalar Fields" branch in the Display navigator. If you activate this option, the program displays a result bubble in the graphic with the smallest and the largest globally occurring result for the following result types:
- Surface pressure
Figure 01 - Max/Min Results in Surface Pressure Plot
- Pressure field
Figure 02 - Max/Min Results in Pressure Field Plot
- Velocity field
Figure 03 - Max/Min Results in Velocity Field Plot
- Surface pressure
AnswerTo display the isosurfaces of the results in monochrome, you have to edit the color scale. To do this, simply double-click the color scale or edit the color scale with the right mouse button (see Figure 01). The slider can then be pushed down so far that only one color remains. This can be changed by double-clicking the color. Then, the maximum value can be transferred manually to the penultimate input field (see Figure 02). If you want a colorless display, define a very small number for the penultimate value. It is also recommended to activate the ‘Outlines of Deformed Surfaces’ option (see Fig. 03).
You can set the display properties of the cross-section outline in the Display Properties dialog box (Options → Display Properties → Edit menu). The settings can be found in the Colors → Extras → External Cross-Section Outline or Colors → Extras → Internal Cross-Section Outline category (see Figure 1). The color, type, and thickness of the line can be set separately for the screen and the printout report.
AnswerMostly, it is in this case so that the 'Action Category - Prestress' in the 'Project Navigator - Display' is hidden. All loads contained in a load case with the action category ‘Prestress’ are no longer displayed in this case. When activating the function, the loads should be displayed as usual.
To adjust the column width individually, right-click the empty gray area in the toolbar. A shortcut menu appears. Select the "Customize" function.
Now, click on the display box of the load case description. It is highlighted in black. Move the mouse to the right edge of the box until the arrow symbols appear on the cursor. Now, you can drag the text box to make it bigger (or smaller).
Check your Windows settings: Region and language. The country or region should be set to Czech Republic and the language should be Czech. In the administrative language settings, click Change System Regional Settings ... and set Czech (see video).
AnswerThe line axis systems can be displayed or hidden by using the Project Navigator - Display.
AnswerIf a user-defined panel has already been created, this color scale is displayed in the Display Properties tab of the 'Printout Report' tab in 'Results' -> 'Palette'. If you set it as the default, the graphics in the report are updated automatically.
For some time, I have to cope with display problems in RSTAB and RFEM that make it difficult to work with the software. It mainly affects the display of results. Depending on the zoom in and out, the lines are extended, dotted or absolutely not displayed.
Do you have any idea how to solve this problem?
AnswerIt might be advisable to (de)activate the hardware acceleration.In RSTAB and RFEM, you can activate or deactivate the hardware acceleration (OpenGL) by using the menu 'Options' → 'Program Options' in the 'Graphics' dialog tab.
In addition, an improved smoothing (antialiasing) can be set in the same dialog box to prevent the edge effect. Both options are only activated after restarting the program.It could also be a problem that the graphics card driver is outdated. Under certain circumstances, this may lead to problems when using RSTAB and RFEM. I would, therefore, ask you to update the driver.

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. ”
