Line statics: User specified starting shape |
The user specified starting shape statics method involves no calculation. Instead, you simply specify the node positions and, if torsion is included, their orientations, directly.
This method allows you to restart calculations using line configurations that have been calculated by separate OrcaFlex calculations. For example you could perform an in-place analysis of a line using its configuration as calculated by an earlier pull-in analysis.
To perform a restart in this way you also need to suppress the other parts of the static analysis by disabling step 2 line statics and whole system statics.
| Warning: | We recommend that user specified starting shape is only ever used to perform restarts as described above. For other static analysis scenarios, this method commonly results in slow and troublesome statics convergence. |
