Markus Baumgärtel Modeling | Loading RFEM

After importing support loads using the "Import Support Reactions as Loads" tool, I noticed discrepancies in the load sums: the loads in the new model are much greater!

Answer

During the import, support reactions are exported as free loads with fixed coordinates. For each of the free loads, you can specify on which surface it should act. During the load transfer, the "All" check box is usually selected (see Figure 01). Thus, all surfaces are loaded that "breach" these individual loads. So it might happen that some surfaces are loaded unintentionally. The result is a greater load sum in the model.

Therefore, it is recommended to specify already in the "Import Support Reactions as Loads" dialog box on which surfaces the imported load may be applied.

In the case of free loads, the surfaces, on which the load should act, can also be adjusted subsequently (see Figure 02).
