  1. Foil Cushion with Material Model Isotropic Plastic 2D/3D

    Nonlinear Material Law for Membranes

    RFEM offers the option to couple surfaces with the stiffness types "Membrane" and "Membrane-Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D" (RF-MAT NL add-on module required).

    This functionality enables the simulation of the nonlinear strain behaviour of, for example, ETFE foils.

  2. Member Hinge Nonlinearity "Scaffolding Diagram"

    The member hinge nonlinearities "Scaffolding - N phiy phiz" and "Scaffolding Diagram" enable the mechanical simulation of a tube joint with an inner stub between two member elements.

    The equivalent model transfers the bending moment via the overpressed outer pipe and after positive locking additionally via the inner stub, depending on the compression state at the member end.

  3. Export of Reinforcement Objects from RFEM to Revit

    Export of Reinforcement RFEM - Revit

    Surface reinforcements defined in the RF-CONCRETE Surfaces add-on module can be exported as reinforcement objects to Revit by using the direct interface.
  4. Automatic Determination of Number of Load Increments

    If the check box "Number of load increments" is deactivated, the number of load increments will be determined automatically in RFEM to solve nonlinear tasks efficiently. The method used is based on a heuristic algorithm.
  5. Adaptive Mesh Refinement

    Adaptive Mesh Refinement

    With this function, it is possible to refine the FE mesh on surfaces automatically. The mesh refinement is carried out step by step. In each step, a new FE mesh according to the numeric error analysis of the previous step will be generated. The numeric error will be evaluated by means of the results on surface elements and is based on the energy formulation by Zienkiewicz-Zhu.
    The error analysis is carried out for a linear static analysis. A load case (or a load combination) is selected for which the FE mesh will be generated. The FE mesh will be used for all calculations.
  6. Member Type "Dashpot"

    The member type "Dashpot" can be used for time history analyses in RFEM/RSTAB with the add-on modules RF-/DYNAM Pro - Forced Vibrations and RF-/DYNAM Pro - Nonlinear Time History. This linear viscous damping element considers forces dependent on velocity.

    With regard to viscoelasticity, the member type "Dashpot" is similar to the Kelvin-Voigt model which consists of the damping element and an elastic spring (both connected in parallel).

  7. Data exchange with Advance Steel using *.smlx files

    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.

  8. Steels according to the Australian standard AS/NZS 4600:2005 in Material Library

    Material Library with Steels According to the Australian Standard AS/NZS 4600:2005

    The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.
  9. TeamViewer in Help menu of RFEM and RSTAB

    Link to TeamViewer in Help menu of RFEM and RSTAB

    By opening the Help menu of RFEM and RSTAB, it is possible to directly access the TeamViewer. Customers with a Service Contract Pro can thus benefit from an easy and quick online support via video conference.

  10. New Project Navigator - Views

    Project Navigator - Views

    Project Navigator - Views allows you to easily generate various views in a few simple steps. Moreover, you can save and open them again at any time.
