I have activated the settlement calculation in FOUNDATION Pro, but can not export the determined stiffnesses of the nodal supports. Why not?


With the default setting calculation in RF- / FOUNDATION Pro, the foundation plate is analyzed as a "slack plate".

However, the export of support spring constants from RF- / FOUNDATION Pro is only available if the calculation has been performed as a "rigid plate" beforehand.

To do this, open the "Details" and the "Settings for the settlement calculation" and select the "Iterative calculation of the reference ground stress by applying a rigid foundation plate". See picture 01.

After the calculation by applying a rigid foundation plate, the option for the export of support spring constants is available in the RF-/ FOUNDA Catalog menu. See Figure 02.
