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. Form-Finding in RFEM

    The RF-FORM-FINDING add-on module in RFEM determines equilibrium shapes of membrane and cable elements. In this calculation process, the program searches for a geometric position for the membrane and cable elements in which the surface tension/prestress of the membranes and cables is in equilibrium with the natural and geometric edge reactions. This process is called form-finding (hereinafter called FF). The RF calculation is activated in RFEM global in the "General Data" of a model in the "Options" tab. After activation, a load case or a calculation process with the name RF-FORM-FINDING is created in RFEM and FF parameters for defining the surface tension and prestress are additionally enabled for the cable and membrane input. Activating the FF option means for the program that before the pure structural calculation of internal forces, deformation, eigenvalues, etc., the form-finding process is always started first and a correspondingly prestressed model is specified for the subsequent calculation.
