    Both RFEM and RSTAB can be the solution . For both programs, there are standards available with which the aluminium and light-weight structures can be calculated and designed.
    In addition to Eurocode 9 with numerous National Annexes, the American standard ADM 2020 is also available.

    Further add-on modules for membrane and cable constructions complete the options.

    Main Programs RFEM or RSTAB
    The main programs RFEM or RSTAB are used to define structures, materials, and actions.

    If you also want to analyze membrane and cable structures, you need RFEM . When it comes to pure beam structures, the purchase of RSTAB is sufficient. In any case, RFEM is the more diverse option because it can be equipped and extended with the corresponding add-on modules for all materials and designs.

    Available standards
    • RF-FORM-FINGING/RF-CUTTING-PATTERN (only for RFEM)
      Determines the shape and cutting pattern for cutting membranes
    • RWIND Simulation
      Complex analysis of any structures in the digital wind tunnel with transfer of load cases to RFEM or RSTAB for further processing.
    Dynamic analysis
    If it is necessary to perform seismic analysis or vibration designs of a building, the RF‑/DYNAM Pro add-on modules provide special tools for determining natural frequencies and mode shapes, for an analysis of forced vibrations, a generation of equivalent loads, or for a nonlinear time history analysis.

    In the case of online training, the communication between the speaker and the participant is live using the Internet. During the training, each participant can ask questions at any time using the chat option.

    For this, you need a reliable and fast Internet connection (for example, DSL) and a headset.

    Your dongle and thus access to your license is only required if you want to carry out the modeling on your computer simultaneously during the online training. In this case, it is recommended to work with two monitors so that you can see both your program interface and the video at the same time.

    If it is not the basic training, the basic knowledge of using RFEM or RSTAB is required.

    Yes, it is possible to exchange data between the LayPLAN software by Layher and RSTAB. The "LayPLAN TO RSTAB" tool allows you this.

    You can easily transfer scaffolding structures to RSTAB. The "LayPLAN TO RSTAB" interface transfers geometry data as well as statically relevant information, such as cross-section and material data, member types, eccentricities, and nonlinear joint definitions according to the approval.

    To operate this interface, an active license of RS‑COM to RSTAB is required.

    A perpetual license or a rental license is available for RS‑COM.
  • Answer

    Dlubal Software has a modular structure. You can compile the software as required. For this, you always need a main program. It is either RSTAB for frame & beam structures, or RFEM for general finite element calculations (beam structures, surfaces, and solid elements). For this, you can configure the required add-on modules depending on your task.
    We can give you general recommendations as to which program combination is possible, but it is better to take some time and select the add-on modules according to the specific needs. The add-on modules that are not required can be simply omitted or quickly reordered if necessary. Therefore, you can only buy the product service that you really need. The programs are also available for purchase without any running costs - an advantage in the eyes of many users.
    We will be happy to advise you in detail and without obligation. A first step is often to familiarize yourself with the trial version or watch some short videos. You can send us a short e-mail or give a phone call and we will show you where to find what.

    If you want to take a look around, you can find the individual solution-related product combinations on our website.

    In order to get an idea of the price, the webshop provides you with a wide range of package composition options, including online ordering and payment. Before the final order, you always have the option to download the product compilation as a non-binding offer. The short video attached shows you how to do it.
