Software for Wind Simulation & Wind Load Generation
RWIND Simulation is a stand-alone program for numerical simulations of wind flows (digital wind tunnel) around buildings or any other objects by means of CFD simulation (Computational fluid dynamics).
The wind simulation can be performed for simple or complex structures. The generated wind loads acting on these objects can be imported to RFEM and RSTAB.
Structural Frame Analysis Software RSTAB
The structural analysis program RSTAB for design and analysis of space frame structures provides a solution for demanding structural engineers. The software meets requirements of modern civil engineering and reflects the current state of the technology.
The structural frame analysis program by Dlubal Software is ideal especially for structural analysis and design of 3D timber structures.

New Program: RWIND Simulation
Wind Simulation (Digital Wind Tunnel) & Wind Load Generation for RFEM or RSTAB
RWIND Simulation is a stand-alone program for numerical simulations of wind flow around structures of any shape.
Structural FEA engineering software RFEM allows easy and effective modeling as well as structural analysis and design of general 2D and 3D structures consisting of member, plate, wall, shell, solid, and contact elements.
Structural frame analysis software RSTAB contains a similar range of functions as RFEM, with special attention to beam, frame, or truss structures. Therefore, it is very easy to use and for many years it has been the best choice for structural frame analysis.

In the course of the expansion of the Dortmund-Ems Canal (DEK), the Ems Canal Bridge (KBr) built in the 1930s at DEK-km 78.806N will be renewed. A double trough is planned for the new building, which is to be erected while shipping is still running.
The Somnium is an accessible roof garden located on the TNF tower (Faculty of Engineering Natural Sciences Tower - TNF) of the Johannes Kepler University Linz (JKU). The TNF tower was built in the 1970s and is the tallest building on the JKU campus with a height of 164 ft. The slender Somnium steel structure was built on the roof of the existing building.
Adohi Hall, which means “woods” in Cherokee, located at the University of Arkansas (U of A) is the first university housing and mixed-use structure of its kind.
The company Under Canvas provides the unique opportunity for all-inclusive adventure glamping (glamorous camping). Established in 2009, the company has since grown to include multiple luxury glamping resorts and customized events all over the country.
Under Canvas began in 2009 with the opening of an all-inclusive glamping adventure package. It has since grown to include eight luxury glamping resorts and a customized event’s offering, bringing the glamping experience to life anywhere in the country.
Four different point-supported glass chandeliers are focal points of the newly renovated shopping mall at Keystone, Indianapolis, USA.
Each chandelier consists of hanging glass plates, which are point-supported from brackets on stainless steel rings.
In September 2017, the Design Building at the University of Massachusetts in Amherst was completed. The $52 million project is one of the largest timber structures in the USA and one of the largest wood-concrete composite projects in the world.
"Thank you for one of the best solutions. I quickly understood the basics using RX-TIMBER.
Hope in future I will buy short term licenses according to the requests from my job."
"I really enjoy watching the webinars you showcase on YouTube. They helped me to convince my client to recently purchase RFEM. They provide a wealth of information.
I really enjoy using RFEM. I've used many analysis softwares in my career but never have I come across a software as powerful and intuitive as RFEM. Thanks for re-sparking a new passion for me.
In just a few weeks, I've been able to use RFEM to analyse some amazing structures, from small to big. I don't understand why everyone is not using Dlubal? It's given my client the edge in this competitive environment.
Keep up the great work."

"I have watched the webinar recording "Design of Cross-laminated Timber Panels (CLT) According to Eurocode 5" on YouTube and I am impressed by about the program and the very good presentation.
" Another very successful webinar, this time on the topic of laminate design.
"We are an engineering office specialized in concrete and metal structures. We have decided to purchase the RFEM software to calculate structures and mechanical components.
For more than a year, it has been a daily pleasure to work with this tool! The support team is attentive with specialist knowledge while the software is intuitive, efficient and extremely comprehensive. Well done!"

"I used this software for my master's thesis and I could handle it very well. It is intuitive and quick to learn; excellent results can be achieved immediately. The only thing I did not like was that I did not have a Mac version, but I hope that it will be available soon. Apart from that it works fine. I can recommend it!"

In RFEM, you can display contact properties between two surfaces by means of contact solids. Among other things, you should ensure that both contact surfaces of a contact solid have the same integrated objects. Therefore, when modeling the contact surfaces, it is recommended to use the copy function in order to create the second contact surface.
This tutorial explains what a force is in mechanics and structural engineering. How is it described in physics and mathematics and how is the force derived from the material density?

Arbitrary point load distributions often occur in the load definition of member structures.
Such load patterns can be edited much faster in the model editing if the relation of the concentrated loads to each other can be made in a definition.
- Current News
By using the helpful add-on modules, it is possible to generate influence lines, moving loads on members and surfaces, and more. Dynamic analysis is also possible as well as required designs of stability, buckling, and fatigue.
The material allocation for hybrid SHAPE‑THIN cross‑sections can be easily selected in RFEM and RSTAB. The prerequisite for that is the allocation of different materials to the cross‑section elements in SHAPE‑THIN.

Because EN 1991-1-4 does not address internal wind pressure for laterally open structures, it is recommended to apply the regulations according to the previous German DIN 1055-4.
This video demonstrates wind flow with simultaneous pressure and suction forces utilizing the "RWIND Simulation" program on four different building types.
