Form-finding
In these analyses, 100% of imposed loads are applied at the start of the analysis. However there may be no external loading required as the form can be generated by finding equilibrium geometry for the prestress state. If no imposed loading is required, input a blank load case.
The analysis proceeds as for the single increment option except the appropriate form-finding properties (soap film or force density) are used for elements where these have been defined. Otherwise uses form-finding uses normal element properties.
