In this tab, the Transformation of the RFEM/RSTAB model is specified. The parameters of displacement (dX, dY, dZ) and rotation (A1, A2, A3) refer to the origin defined in the Dlubal application, taking into account the wind direction of the relevant load case and the size of the wind tunnel.
The Scaling options enable you to change the model size in one or more directions. S1 is the axis in the wind direction, S2 transversal to it, while S3 represents the vertical axis. If you want to scale the model uniformly in all directions, select the Lock aspect ratio option.
In a similar way, the Skewing parameters enable you to distort the model. K1 is the axis in the wind direction, K2 transversal to it, while K3 represents the vertical axis for rotation.
