In addition to our technical support (e.g. via chat), you’ll find resources on our website that may help you with your design using Dlubal Software.
Frequently Asked Questions (FAQ)
Customer Support 24/7
AnswerIn RSTAB and RFEM, you can create combinations automatically according to different standards. In the case of a purely linear calculation, the generation of result combinations can be defined in the model general data. The attached video shows the automatic generation.
A solid must always be completely closed. To clarify the problem, imagine filling the solid with a liquid. At no point should liquid escape from the solid.
The attached video shows how to insert the missing surfaces easily and effectively.
AnswerSimilarly to surfaces, there are various smoothing options for displaying the results of support reactions. For a nonlinear support, you should always select the actual distribution to display the results.
AnswerIn RFEM, the easiest way is to use the "Plane Surfaces" → "Annulus" feature. This allows you to model the reinforcement rings very quickly and easily. Then you can extrude the inner line into a surface, the chimney is already generated. Now, the existing annular surface is copied upwards and the corresponding stiffeners are modeled. You can use the "Rotate" command to distribute the stiffeners over the chimney perimeter.
AnswerIn the CRANEWAY program, you can select the display of load combinations for the individual design situations in the middle of Window 1.5 Load Combinations.
AnswerIn RWIND Simulation, you can manually adjust the model position and the model rotation. To do this, simply select Model → Edit in the navigator, and then enter the desired rotation angle in the Position tab. In this case, the rotation is carried out without changing the displacement.
AnswerThe error message indicates that no option was found to define the required reinforcement for the mats and rebars selected from you.After clicking OK, you will automatically be redirected to Window 1.3. Here, please select additional mats and/or rebars and then perform the design again.
AnswerYes, that is possible. Simply select the structure to be copied. Make sure that the line releases and all released objects are also selected. Now you can create a copy with the 'Move and Copy' function.
AnswerIn RFEM, it is possible to search for FE mesh nodes using the menu 'Edit'→ 'Find by Number'. An existing FE mesh is of course a prerequisite.
AnswerThe easiest way to find a member is to select Project Navigator - Data. Here, right-click the members and select "Find Members." Now you can enter the member number and the member is marked with an arrow in the graphic.

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. ”
