Respuesta:
El proceso de búsqueda de forma en RFEM busca formas en equilibrio, considerando el pretensado de la superficie y las condiciones de contorno dadas. La tensión superficial para este análisis se define en las definiciones de la propiedad del elemento pertinente. 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. Las cargas dadas se "memorizan" en el modelo para el cálculo de búsqueda de forma.
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.
