Why Dlubal Software?
Wind Simulation & Wind Load Generation
With the stand -alone program RWIND Simulation, 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.

Webservice and API | Benefits
Webservice and API clearly cover the universal aspects in the construction industry. However, the calculation and design require different features for each region, country, company, and civil engineer. Webservice and API allows each user to create their own analysis and design system easily while trusting the performance and reliability of RFEM / RSTAB.
There is an increasing need for the customized and automated structural analysis and design. The technology of Webservice allows you to create special functionalities quickly and precisely. Our customers can develop such solutions independently or in cooperation with us.

Webservice and API | Application Areas
Webservice and API can be used in various ways. In the following text, you can find some ideas how the Webservice and API can support your company:
- Creating additional applications for RFEM 6 / RSTAB 9
- Possibility to make our workflows more efficient (for example, model definition and input) and to integrate RFEM 6 / RSTAB 9 into your company applications
- Simulating and calculating several design options
- Running optimization algorithms for size, shape, and / or topology
The quality level of your work is automatically increased, not only by the algorithmic model definitions, but also by:
- Extending / consolidating RFEM 6 / RSTAB 9 with your own controls
- Increased interoperability between the individual software used to complete a project

Webservice and API | What is Webservice and API?
Webservice and API is an XML-based information exchange system for a direct client-server communication. These systems can include programs, objects, messages, or documents. For example, a web service protocol of the HTTP type runs the client-server communication when a user searches for something using a search engine.
In our case, the client is your programming environment (.NET, Python, JavaScript) and the service provider is RFEM 6. The client-server communication allows you to send requests to and receive feedback from RFEM/RSTAB.
What is the difference between Webservice and API?- Webservice is a collection of open source protocols and standards used to exchange data between systems and applications. API is a software interface that allows two applications to interact with each other without the user being involved.
- All web services are APIs, but not all APIs are web services.
What are the advantages of the Webservice technology?- Faster communication within and between organizations
- Service independence from other services
- Webservice allows you to use your application to make a message or a feature available to the rest of the world.
- Webservice helps you to exchange data between different applications and different platforms.
- The applications can communicate, exchange data, and share services with each other.
- SOAP ensures that the programs created on different platforms and based on different programming languages can exchange data securely.

Webservice and API | Languages Supported
In theory, a web service can be created with any programming language. However, we at Dlubal Software have created high-level function libraries for our users. With these high-level function libraries, you can create powerful scripts by simple programming. These libraries include:
- Python high-level functions
- C# high-level functions
We decided to use these programming languages for a specific reason. Python in particular has the following features:
- Simple and easy to learn
- Still very powerful
- Many extensions and libraries available
- Many resources available on the Internet

Steel Joints | Stability Analysis Software
For the joint components, it is possible to check whether the stability failure is relevant (requires the Structure Stability add-on for RFEM 6 / RSTAB 9).
In this case, the critical load factor for all analyzed load combinations and the selected number of mode shapes is calculated for the connection model. The smallest critical load factor is compared with the limit value 15 from the standard EN 1993‑1‑1, Clause 5. Furthermore, a user-defined adjustment of the limit value is possible. Moreover, the corresponding mode shapes are displayed graphically as the result of the stability analysis.
For the stability analysis, an adapted surface model is used to specifically recognize the local buckling shapes. The model of the stability analysis, including the results, can also be saved and used as a separate model file.

Concrete Design | Graphical Display of Cross-Section Stresses
The existing stresses and strains of a concrete cross-section and the reinforcement can be displayed as a 3D stress image or 2D graphic. Depending on the selected results in the result tree of the design details, the stresses or strains are displayed in the defined longitudinal reinforcement under the load actions or the limit internal forces. -
Concrete Design | Determination of Deformation in State II
The deformation is determined for members and surfaces, taking into account the cracked (state II) or non-cracked (state I) reinforced concrete cross-section. When determining the stiffness, the tension stiffening between the cracks, the so-called "tension stiffening," can be considered according to the design standard used. -
Concrete Design | Definition of Effective Slab Widths of T-beams by Segment
Within a member, you can define the integration width and effective slab width of T-beams (ribs) with different widths. The member is divided into segments. The transition between the different flange widths can be either graded or specified as linearly variable. For the reinforced concrete design of the rib, the defined surface reinforcement can be considered as a flange reinforcement. -
Concrete Design | Definition of Surface Reinforcement
The surface reinforcement is entered directly on the RFEM level. The defined surface reinforcements can be selected individually and the usual editing functions Copy, Mirror, or Rotate can be used when entering the surface reinforcement.
