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)

For surface supports, this option is only available if a nonlinearity in the local z direction has also been defined (failure if contact stress in z is negative/positive). In the dialog box where you can edit the nonlinearity, there is the option "Friction in plane xy".
This option works as shown in the graphic dialog box: The support in x and y direction is only completely assumed when the contact stress Tau (contact stress sigma by friction coefficient) is reached. Before this is reduced linearly.
In order to use this option, it is necessary to define a support in the horizontal directions. It can be defined as fixed or with an elastic spring. If the spring is defined with 0, no support is considered even when a friction coefficient is entered.
AnswerIf you are using members with cross-sections, which are not known be the interface, you should use the mapping file for cross-sections. The mapping file can be easily filled with the names of the cross-sections. In the left column of the table write the names of cross-section used in TEKLA and in the right column you write the DLUBAL names or select them from the library.Please check the attached video.Note:
In TEKLA you have to have loaded the right environment. In the video Chinese cross-sections should be transferred, so the Chinese environment has to be used in TEKLA.
Define a suitable load case to correctly combine the planned prestress with the other load cases and apply a "pulling" strain to the members affected. A pulling strain load can, for. B.
Input via a Longitudinal Displacement is the most comprehensible input because you can directly measure the offset on the turnbuckle of a tension member.
- a negative temperature load T c distributed uniformly over the cross-section,
- a negative change in length ε,
- a negative longitudinal displacement Δl,
- a positive initial prestress V or
- its positive final prestress V only in RFEM.

AnswerFor this case, the "Stiffnesses" member type is available. You can specify the member stiffnesses directly in a dialog box that you open with the [Edit] button. Thus, the assignment of a cross-section is unnecessary.
AnswerThe program RWIND Simulation can be tested as TRIAL for 30 days.
In our programs, we use the operating system's fonts.It is necessary to change the region in the operating system's Control Panel. Then, restart the computer. The texts should then be displayed correctly.
AnswerFor irregular member structures, the load generators "From Area Load on Members via Plane" or with "Cells" can be helpful. However, both functions assume that the nodes of the members lie in one plane. In the settings of the load generators, you can increase tolerances for the nodes to also detect nodes that lie outside the plane (see Figure 01). In interaction with the "fictitious lines", it is possible to load even more complex structures.
You can adjust the column individually according to your wishes.
Go to the toolbar and right-click in the empty gray area. Then, go to "Customize".
Now, click the Load Case Description window and it will be highlighted in black.
Now you can go to the right edge of the window and extend it.
AnswerAccording to the default setting in the program, it is defined that the loads act on all surfaces.However, if there is no surface available in the file, the load can not act and the warning is displayed. If the message is confirmed by clicking "OK," the load is still imported into the model but not applied to any surface. However, as soon as a surface is subsequently defined, the imported loads can act on it.
