Programmable COM Interface for RFEM/RSTAB

The RF-COM/RS-COM add‑on module is a programmable interface (API) based on the COM technology. This interface allows you to customize the main programs RFEM and RSTAB to meet your individual needs and to add customized input macros or post‑processing programs.

  1. 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.

  2. Program code in Visual Studio

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