  • RWINd Simulation

    Software for Wind Simulation & Wind Load Generation

    RWIND Simulation is a stand-alone program for numerical simulations of wind flows (digital wind tunnel) around buildings or any other objects by means of CFD simulation (Computational fluid dynamics).

    The wind simulation can be performed for simple or complex structures. The generated wind loads acting on these objects can be imported to RFEM and RSTAB.
