Analysis Wizard : Form Finding

Definition

Form-finding Properties

The analysis proceeds as for the single increment option except that no results are stored. Instead, the resulting deflected coordinates and equilibrium element distortions overwrite the original data to create a modified data file.

Soap-film form-finding

The analysis proceeds as for the single increment option except soap-film properties are used for elements where these have been defined. The resulting deflected coordinates and equilibrium element forces overwrite the original data to create a modified data file.

Force-density form finding

The analysis proceeds as for the single increment option except force density properties are used for elements where these have been defined. The resulting deflected coordinates and equilibrium element forces overwrite the original data to create a modified data file.

Post Analysis

Spacer element are used to control form-finding and avoid poor meshes. Post analysis it is possible to save axial forces generated in spacer elements as prestress

Beam and similar element also generate load axial forces which can be stored as prestress.
