Frequently Asked Questions (FAQ)

Please note that in the first "Main" tab of the Base data, it is necessary to select both the "3D" and "Solids" types of models as the main objects to activate. As soon as you make these settings, as shown in the image below, you will be able to use the add-on and activate it then.

The university licenses of RFEM 6 and RSTAB 9 are controlled by a collective user. The license can only be used on the computers logged into the Dlubal license server by using the university's public / static IP address.

Therefore, the following information is required:

1. Email address of the collective user (functional email address)

2. Number of licenses

3. Public / static IP address of the university gateway It is possible to specify an IP address range here.

After successfully creating the license, you can use the university license with the login data of the collective user (a password provided by Dlubal).

We no longer offer such model generators in RFEM 6. Now, you can use the "Dlubal Center → Blocks" to create some predefined structures.

These structures are defined by parameters and can easily be changed as required.

The value "V_Ed" from the concrete design does not exist in the static analysis.

However, you can display the result "v_max,b" from the main internal forces of the surface. The concrete design uses exactly this "v_max,b" as "V_Ed."

Yes, you can. To do this, click on "Calculate" in the menu bar and on "To calculate ..." in the menu selection.

The "To be calculated" dialog box opens, where you can select the load cases/combinations and add-ons that you want to apply to the calculation.

By clicking "OK", the calculation starts.

Releases for warping are at each member end by default. Splitting members leads to a warping release.

If you do not want to have a warping release there, but rather continuous warping, you need to define a member set. If activating the "Torsional Warping" add-on, the warping is transferred automatically. If this is not desired for the member set, select the "Discontinuous torsional warping" option, see the image.

Data communication cannot be completely avoided. RFEM 6 can only be used with an online license. So you need to log in. After logging in, a local license will be downloaded to your computer for a period of 24 hours, unless you specify other setting.

The program communicates with the server only when starting the application, displaying the License Manager, or in case the local license is about to expire. This is then extended during the communication with the server. 100 KB should be sufficient for one communication with the server.

More data can be required when sending diagnostic data, but you can turn it off in Program Options. Additional data can be sent after a program crash, but it is up to the user whether to send the data.

You can save your printout reports as a template and use them on other computers.

Export GUI Settings

On another computer, open the "Options" menu and select "Export GUI Settings." The "Export GUI Settings" dialog box appears where you can select the settings to export and then save the file in the *.rf6.gui format.

Import GUI Settings

On your computer, open the "Options" menu and select "Import GUI Settings." The "Import GUI Settings" dialog box appears where you can open the*.rf6.gui file. Then, select the parameters to import.

An information window appears, saying that it is necessary to restart of the software.

Load from Template

The new printout report templates are then available in the Printout Report Manager upon clicking the "Load from Template" button.

The geometry of the soil solids of a soil massif can be edited manually as soon as you set the "Set of Soil Solids" type in the input dialog box.

Step 1 (optional) - Soil Massif from Soil Samples

It is first possible to generate the massif from soil samples in order to use the advantage of the generated soil solids with the soil materials and layer interfaces, resulting from the data of the soil investigations contained in the soil samples. This can be done in a first step, as shown in Image 01.

Step 2 - Setting the Set of Soil Solids Type

In the second step, you can change the soil massif type from (1) Generated from Soil Samples to (2) Set of Soil Solids. After you confirm this step, the calculated coordinates of the soil massif appear. Image 02 shows this step in the Soil Massif dialog box.

Note: It should be noted that the "generated" status is canceled by this step; which causes, among other things, that the connection to the soil samples is split in order to allow for editing the soil solids.

Step 3 - Editing Geometry of Soil Solids

You can now edit the soil solids and create the desired geometry of the terrain surface by using all the tools available and known in RFEM 6. You can see this step in Image 03.

The following image shows an example of the soil massif geometry created in compliance with Step 1 to Step 3.

To use numerical methods, such as FEM, in geotechnical engineering, it is reasonable to set the cohesion as not equal to zero. Therefore, a small cohesion between 0.5 and 1.0 kN/m² can be applied even for non-cohesive soils.
