Combine Results with Results from Previous Static Analysis
Use this option to combine results from the included static analysis with the results of a prestress static analysis.
The engine adds the stresses and displacements from the previously run static analysis to those from the current prestress static analysis when it calculates results for the prestress analysis. However, the resultant force that is given in the summary file and the reactions at point constraints that are given in Results do not include the forces from the previous static analysis.
The engine multiplies the previous static results by the before adding them to the prestress analysis results.
Use caution when interpreting combined results since there are no restrictions on loading and constraint sets used for the prestress and previous static analysis.
