• ### How do the network licenses work and how often is it possible to license a program to it?

New FAQ 003417 EN

Generally, two things are required for the licensing:
2. corresponding authorization file
The license key can be provided via a USB dongle or by means of a network softlock on a central company server. For the licensing from perspective of a client, there must be a permanent connection to the server. Once a license has been assigned, it can be viewed on the web-based license surface at http://localhost:1947/_int_/sessions.html. An automatic timeout after 12 hours of inactivity prevents a license from being permanently assigned and releases it to other users.
With the most recent generation of license keys, it is possible to activate 50 licenses per program and add-on module. This means that you can access RFEM and RF-STEEL EC3 from a maximum of 50 computers at a time.
• ### Why is a transversal compression factor kc,90 of 1.0 assumed in the support compression design?

New FAQ 003381 EN

For concentrated loads in the vicinity of the support, it is mandatory to apply the smaller transversal compression coefficient of kc,90 according to Section 6.1.5 (4) of the Eurocode 5.

Optionally, it is possible to deactivate the support compression design in the program RX-TIMBER and to do corresponding transversal compression  reinforcements.

If the entered concentrated load is not relevant for design, the user has the additional option to assign the transversal compression factor with a user-defined assignment (Figure 3).
• ### I have purchased the programs RFEM and RSTAB. In My Account on the Dlubal extranet site, however, it is possible to see only RFEM (or only RSTAB) in the download area. Why is that?

New FAQ 003337 EN

Whether or not the download for RFEM or RSTAB is displayed in the download area of the Dlubal account depends on whether or not you have concluded a service contract for the respective product.

If a service contract has been concluded for the respective product, the links for this product are visible.

If no service contract has been concluded, no links are visible.

If you purchase RFEM or RSTAB without a service contract at a specific time, you are entitled to use this program version. If you need the download link for the purchased program version, you can download it on our homepage in the "Previous Program Versions" section.

• ### Is it also possible to edit the loads applied in RX-TIMBER?

FAQ 003198 EN

• ### When I open the Windows calculator in Dlubal Software, an error message appears. The calculator will start, however, it is not possible to import the results directly. What is the reason?

FAQ 003138 EN

Unfortunately, the calculator implemented in Windows 10 is not compatible with our programs. You can use e.g. the “Copy” option to paste the values into the clipboard and then paste them into the program to still use the calculator. A better alternative is to replace the Windows 10 calculator with Windows 7 or Windows 8. There are sufficient instructions on the Internet to carry out this procedure. It is only necessary to make sure that the file calc.exe in the Windows folder C:\Windows\System32 starts the old calculator afterwards. The Windows 7 calculator can then be used as usual after importing the results.

• ### Is it possible to open RX-TIMBER files in RSTAB and RFEM?

FAQ 003133 EN

To open an RX-TIMBER file in RFEM or RSTAB, select the option “All Files (*.*)” as “File Type” (see Figure 01). The geometric data, loads as well as load combinations will be imported. Settings relevant for the design, for example, shear force reduction, fire protection definitions, serviceability limit state parameters, etc., are not applied and must be redefined in RF-/TIMBER Pro.

If the model does not appear in the work window, display the view with the option “Show Whole Model” (see Figure 02).

• ### How can I change the language of the RX-TIMBER add-on module?

FAQ 003131 EN

Contrary to RSTAB and RFEM, you can find the language setting of the RX-TIMBER add-on module in the project manager of the program. The corresponding setting can be found under "Edit" in the menu bar (see Figure 1).

• ### The RX-TIMBER module contains the function called "Boundary Beam". What exactly does this option do?

FAQ 003050 EN

By means of this option, it can be determined whether a boundary beam shall be designed or an inner beam that is arranged between the individual panels. The design load differs as follows:

Inner beam:
${\mathrm q}_{\mathrm k}\;=\;{\mathrm q}_{\mathrm k'}\;\cdot\;\mathrm a\;\cdot\;\mathrm k$

Boundary beam:
${\mathrm q}_{\mathrm k}\;=\;{\mathrm q}_{\mathrm k'}\;\cdot\;\left(\frac{\mathrm a}2\;+\;\mathrm ü\right)\;\cdot\;\mathrm k$

a = beam or rafter spacing
ü = roof overhang at the gable
k = load factor for continuous effect
pk' = surface load in kN/m²

The application area is shown in Figure 02.

• ### The dimensioning in the graph is, depending on the system, in the expression of RX-TIMBER is very confusing. Can you optimize this?

FAQ 002962 EN

By default, the graphic is only printed in the report at more than 40% of the page height. In some cases, it may be useful to display the graphic printout over the entire height of the page and to rotate the graphic by 90 ° (see Figure 02). Normally, it should be sufficient to display the dimensions with two decimal places in order to save space. This setting can be defined in the menu "Units and Decimal Places" (see Figure 03). Finally, the auxiliary lines can be shortened and the font size can be reduced (see Figure 04). A font size of 5 should be sufficient for an A4 printout. To select a small font size, you should use the "Small Fonts" font. The finished result is shown in Figure 05.
• ### How can I read the authorization file (AUTHOR.INI) in an RX-TIMBER module?

FAQ 002917 EN

Reading in is done directly in one of the additional modules and not via the project manager. Please start one of the licensed modules and select in the menu item "Help" the option "Read authorization file ..." (see picture 01). Enter the path where you copied the authorization file and complete the process.

In addition, if there is a problem with licensing, please send us the diagnostic file for authorization. These can be created in the menu item "Help → System diagnostics" (see Fig. 02).
