Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

  1. Export Option " Update only materials, thicknesses, and sections

    Updating the Revit Model

    The direct interface with Revit allows you to update the Revit model according to the changes you have made in RFEM or RSTAB. Depending on the modification, the Revit objects may have to be regenerated (deleting the object and subsequent regeneration). The regeneration is performed on the basis of the RFEM/RSTAB model.

    If you want to avoid this regeneration, activate the option "Update only materials, thicknesses, and sections." In this case, only the properties of the objects will be adjusted. Changes differing in material, surface thickness, and section are, however, not considered in this case.

  2. Export of Reinforcement RFEM - Revit

    Surface reinforcements defined in the RF-CONCRETE Substructures add-on module can be transferred to Revit as reinforcement objects via the direct interface. Surfaces, rectangles, polygons, and round reinforcement areas can optionally be selected in RF-CONCRETE Surfaces for this purpose. In addition to rebar reinforcement, it is also possible to transfer rebar reinforcement.
  3. Data Exchange with Advance Steel Using *.smlx Files

    When exchanging data with Advance Steel using *.smlx files, the interface is automatically detected. This means that *.smlx files are possible even if no version of Advance Steel is installed.

  4. Input Generator for more field-ceiling plate created in VBA (MS Excel)

    RF-COM/RS-COM | Scope of Functions

    • Reading and writing access to structural data, load case data, load and result combinations, and calculation results
    • External control of calculation
    • Possibility to open and edit available models or to create new models
    • Access to all results such as deformations, internal forces, and support reactions
    • Ability to intercept possible errors using error messages
    • Access to control elements as well as results of the following programs:
      • RF-/STEEL
      • RF-/STEEL EC3
      • RF-/ALUMINUM
      • RF-/CONCRETE
      • RF-STABILITY
      • RX-TIMBER Glued-Laminated Beam
      • RF-/TIMBER Pro
      • RF-/DYNAM Pro
      • SUPER-RC
  5. RF-COM/RS-COM | Features

    RF-COM/RS‑COM creates RFEM/RSTAB models and write data as well as load cases, load and result combinations.

    RF-COM/RS‑COM consists of an instruction set that can be embedded in common programming languages, such as Visual Basic, Visual Basic for Applications (VBA), Visual C++ (also .NET). The instruction set includes objects and methods that allow access to the RFEM/RSTAB data.

    To be able to use RF-COM/RS‑COM, you only need an editor, a compiler and basic programming knowledge. You can easily integrate the supplied object library to the editor. For example, in the case of Microsoft Excel, you have everything you need as a VBA editor is included in this software.

    The RF-COM/RS‑COM interface requires valid licences for RF‑COM/RS‑COM as well as for RFEM/RSTAB and the respective add‑on modules whose data is to be used.

    Application Areas of RF-COM/RSCOM

    • Structure generator for typical geometries with loading and combinations
    • Importing and exporting data from spreadsheet programs such as MS Excel and MS Access
    • Connection to various programs compatible with COM, for example CAD systems
    • Customized pre- and postprocessing modules
    • Processing and results of data in user-defined formats
  7. RF-LINK | Standard ACIS Text Format (*.sat)

    The ACIS SAT file format is smaller than other 3D formats, saving you time when importing and exporting models. Currently, the export supports the format ACIS 7.0.

    In addition, SAT is considered to be particularly robust, and all geometry and topology data, where relevant in RFEM, is retained in the highly accurate SAT models.

  8. Result of transfer 1

    RF-LINK | Initial Graphics Exchange Specification (*.igs, *.iges)

    The Initial Graphics Exchange Specification (IGES) defines a neutral, highly independent data format, which is used to exchange digital information among Computer Aided Design (CAD) programs.

  9. Result of transfer 2

    RF-LINK | Standard for the Exchange of Product Model Data (*.stp, *.step)

    The STEP format represents a standard interface initiated by ISO (ISO 10303). In the topology specification, all shapes (line, surface and solid models) relevant for RFEM can be transferred from CAD models.

    Note: This format is completely different from the product interface DSTV (Deutscher Stahlbau Verband), which uses the same file extension *.stp.
