Is it possible to analyze a frame structure behind a building envelope with RWIND Simulation without modeling the building envelope? The loads should be distributed among the members.

Answer

If the building envelope is not modeled, the wind load in RWIND Simulation only attacks the surfaces of the members. Elements that would distribute the pressure between them on the members do not exist. In this case, the function "Close Holes" is not suitable for replacing the surfaces. Thus, an automatic transfer of the wind load to RSTAB or RFEM is not possible.

However, you can model the building envelope in RFEM in a separate model and have it analyzed in RWIND Simulation. The wind pressure can then, for. For example, you can create them manually as load with the load generators. The procedure is shown in the video.
