Wind Simulation & Wind Load Generation

With the individual program RWIND 2 , wind currents around simple or complex structures can be simulated using a digital wind tunnel.

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

  • Shifted Display of Nodal Loads



    RFEM 6

    RSTAB 9


    Would you like to display nodal loads or load components acting in one point in parallel? Then use the "Shifted Display" option. This allows you to define offsets in the x, y, and z directions, as well as the size and spacing.

  • Shear Resistance of Bolts

    To determine the shear resistance of bolts, you can use the Steel Joints add-on to specify whether there is a shaft or a thread in the shear plane.

  • Material of Weld

    Is there a weld seam connecting two plates with different materials? Now, you can select from a combo box in the Steel Joints add-on which one of both materials should be used for the weld seam.

  • Multiple Editing of Member Reinforcement

    Utilize this time-saving step! This feature allows you to define or edit the member reinforcement for several members or member sets at the same time.

  • Design of Orthotropic Timber Surfaces and Cross-Laminated Timber (CLT)

    Do you work a lot with timber? In the Timber Design add-on for RFEM, you can design members as well as surfaces according to the Eurocode, such as cross-laminated timber, glued-laminated timber, softwood, engineered wood, and so on.

  • Design of Surface Reinforcement

    You have the option to automatically design the existing surface reinforcement to cover the required reinforcement. You can also select whether to automatically define the reinforcement diameter or the member spacing.

  • Intersection of Curved Surfaces and Solids



    RFEM 6


    Curved elements are available only in RFEM. It's possible to intersect curved surfaces and solids.

    When doing this, the program generates surfaces with the "Trimmed" surface type. With this technology, you can create very complex geometries, such as pipe intersections or curved openings, with a single click.

    The intersection of solids is carried out adaptively using the new solid types "Hole" and "Intersection", according to the set theory. Use this method to create new, complex solid geometries similar to the manufacturing process (drilling, milling, turning, etc.). Therefore, it is possible to create complex curved surface or perforated solid elements. It's a simple process!

  • Editor for Mesh Refinement Control

    Do you already know the editor for mesh refinement control? It is a great help for your work! Why? It's easy – it gives you the following options:

    • Graphic visualization of the areas with mesh refinements
    • Mesh refinement of zones
    • Deactivating the standard 3D solid mesh refinement with transversion into the corresponding manual 3D mesh refinements.

    These options help you to formulate a suitable rule for meshing the entire model, even for the models with unusual dimensions. Use the editor to efficiently define small model details on large buildings or detailed meshing areas in the coating area of the model. You will be amazed!

  • Freely Adjustable Wind Permeability for Surfaces

    Use RWIND 2 Pro to easily apply a permeability to a surface. All you need is the definition of

    • the Darcy coefficient D,
    • the inertial coefficient I, and
    • the length of the porous medium in the direction of flow L,

    to define a pressure boundary condition between the front and back of a porous zone. Due to this setting, you obtain the flow through this zone with a two-part result display on both sides of the zone area.

    But that's not all. Furthermore, the generation of a simplified model recognizes permeable zones and takes into account the corresponding openings in the model coating. Can you waive an elaborate geometric modeling of the porous element? Understandable – we have good news for you then! With a pure definition of the permeability parameters, you can avoid complex geometric modeling of the porous element. Use this feature to simulate permeable scaffolding, dust curtains, mesh structures, and so on.

  • Creating RSECTION Cross-Section from DXF File





    Would you like to create a cross-section from the import of a DXF file? It's very easy. You have the following options:

    • Create elements automatically
    • Use DXF template lines as centerlines of elements with a defined thickness

    Do you select the option to create the elements automatically? In that case, the program creates the elements and the associated parts for you from the contour of the outline. It only creates the elements not exceeding a definable maximum thickness. Do you have the cross-section geometry as a gravity line model? Then use DXF template lines as centerlines of elements with a defined thickness. Define a thickness that is assigned equally to all elements. Do you miss the "Create elements automatically" and "Create elements on lines" functions? Don't worry, both are also available in the "Edit" menu under "Manipulation."
