Proces znajdowania kształtu (form-finding) w programie RFEM wyszukuje kształty w stanie równowagi, z uwzględnieniem wstępnego naprężenia powierzchni i zadanych warunków brzegowych. The surface stress for this analysis is defined in the relevant element property definitions. The program can also consider additional loads during the form-finding calculation in the load cases defined with the "Form-Finding" action category.
Since RFEM runs the form-finding analysis before the calculation of all other load cases and load combinations while considering the form-finding settings in the element properties and loads in the load cases with the "Form-Finding" action category, the calculation of the load cases with the "Form-Finding" category for the determined shape provides no relevant information for the structural design. The load cases with the "Form-Finding" category are only provided as an input for the form-finding analysis. The given loads will be "memorized" in the model for the form-finding calculation.
Therefore, the "Calculate All" command neglects these special load cases with the "Form-Finding" category and only calculates the load cases which will be applied on the final shape of the structure.
