I am looking for a way to roll out RWIND using software deployment. Unfortunately I can not find an MSI file.
Answer
The RWIND installation program allows automated electronic software distribution, also known as a silent (unattended) installation. In the Silent mode, there is no need for a user to monitor the installation and provide input via dialog boxes. The Silent installation runs on its own, without any end-user intervention, which may be very useful when installing RWIND on a large number of computers, for example in a computer classroom.
The silent installation consists of two steps:
1. Recording parameters for the silent install. Run the setup with the -r parameter to select setup options and automatically record the InstallShield Silent Response File (Setup.iss).
2. Running the silent install (repeatedly). Once the Silent Response File is ready, you can run the setup with the -s parameter, which installs RWIND in the silent mode according to parameters stored in the Silent Response File.
Example:
Let's assume that you have downloaded RWIND installation program RWIND_2.02.2230.exe and saved it to N:\Tmp_RWIND directory on a shared network drive. You can then create two batchfiles for the silent install:
Batchfile N:\Tmp_RWIND\Silent_Install_RWIND_Record.bat for recording of installation parameters with content:
"N:\Tmp_RWIND\RWIND_2.02.2230.exe" /a /r /f1"N:\Tmp_RWIND\Setup.iss"
and batchfile N:\Tmp_RWIND\Silent_Install_RWIND_Play.bat for the silent install with content:
"N:\Tmp_RWIND\RWIND_2.02.2230.exe" /a /s /f1"N:\Tmp_RWIND\Setup.iss"
Run Silent_Install_RWIND_Record.bat from one of your computers and create the InstallShield Response File (Setup.iss) in N:\Tmp_RWIND directory. Note that you can also create/edit the response file manually in a text editor (Notepad.exe). After creating the Response file, you can run Silent_Install_RWIND_Play.bat on all other computers to install RWIND silently.
You can also download the batchfiles here FAQ 005346 | Silent Installation RWIND
RWIND_Silent_Install_Batchfiles.zip but remember that you have to modify them according to your real names and paths.
Note that these batchfiles require elevated privileges, i.e. to run the batchfile, click on the file by right mouse button and select "Run as Administrator".
When importing a cross-section from RSECTION 1, I get an error message regarding the version. What can I do?
Answer
This error message is displayed if you are using a newer version of RSECTION 1 than RFEM 6.
Both versions should be on the same level in order to ensure the data compatibility of both programs, otherwise the new features of RSECTION 1 are not yet available in RFEM 6.
Make sure both versions are up to date.
My old model is suddenly unstable. What can be the reason?
Answer
As of RFEM 5.27, there has been an adjustment in the solver that should better recognize hinge chains, which can make models unstable in the newer versions.
Adjustments in the solver regarding the consideration of line hinges - hinge chains (two surfaces each with a line hinge for the rotation about x on the same line) now lead to instabilities.
Please check your model accordingly.
- Double line hinges
- Line hinges on free surface edges
There are no automatic load combinations created. What can I do?
Answer
First, check whether you have activated the Combination Wizard and assigned it to a design situation.
Then, check the settings of the Combination Wizard. To get the automatically generated load combinations, you need to deactivate the "User-defined action combinations" option.
I get Error 1327: Calculation failed. What can I do?
Answer
In many cases, Error 1327 describes inconsistencies that arise when transferring the data to the solver. You can proceed as follows:
- Check whether you are using the current customer version. As an alternative, download the current customer version from the Extranet.
- Check whether there is enough space available on your hard drive C:\.
- Contact Dlubal support with the file that contains no results and describe when the error occurs.
The result of extreme values is not displayed. Where can I activate the max/min information?
Answer
If the max/min information is no longer displayed, please check whether you have activated this in the Navigator - Results.
I would like to determine and consider the stiffness of a line support using a fictitious wall. Why is this option grayed out?
Answer
The "Stiffness via fictitious wall" option is only available if you have selected the local axis system of the supported line, not the global coordinate system.
Once you select "Local xyz" under the coordinate system and activate the option, the "Stiffness via fictitious wall" tab becomes available. See also Image 01 and Image 02.
When exporting my model from RFEM to RWIND, I get the message "Warning No. 7731 | Reading of logger file failed." What can I do to start the simulation in RWIND?
Answer
When using couplings/rigid members or members with a cross-section of the Dummy Rigid type, problems often arise when generating models in RWIND. The program stops, giving the warning message shown in Image 01.
However, you still have the option to run a wind simulation for such structures. To do this, deactivate the visibility for the objects concerned, for example, using the View navigator (see Image 02).
Then, in the "Simulate and Generate Wind Loads" dialog box, the "Settings" tab, activate the "Export active objects only" option (see Image 03).
You can then open the model in RWIND or simulate it directly in the background.
What is the difference between RWIND 2 Basic vs. Pro?
Answer
The most significant difference between the RWIND 2 Basic vs. Pro options is the simulation type. The Basic edition applies a steady-flow simulation. The Pro edition contains everything that is available in the Basic edition, but also provides new options and features including the transient flow simulation using a more advanced turbulence model (Spalart-Allmaras DDES).
For a full list of features compared in both versions, please refer to the RWIND 2 online manual RWIND Basic and RWIND Pro section with the link below.

Check out these tips to help you get started with the RFEM and RSTAB programs.Wind Simulation & Wind Load Generation
With the stand-alone program RWIND 2, you can simulate wind flows around simple or complex structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.★ ★ ★ ★ ★Your support is by far the best
