View derived result that combines multiple load cases together.
Before you begin, you must have one or more linear
structural, multi-loadcase or thermal analysis results.
Linear superposition is mathematically represented by the following equation:
Where,
A vector of results (displacements, stresses, strains, and so on) for
each individual load case.
Scale factor.
Common usage examples are for structures with varying loads under
operation. Not all loads are active at the same time, so a set of possible unit
loads cases is created then combined later with varying scale factors to find the
worst combination of loads.
The principle of superposition is applicable to
linear analysis within a single design study. Non-linear analyses are not possible.
In SimSolid, results superposition is supported for
linear static and thermal analysis load cases only.
On the main toolbar, select Post study.
Select either Structural superposition or
Thermal superposition.
In the dialog, hold down Control
+ Shift and select the results to
combine.
Click the button to combine analyses.
Click Solve.
All combined results will be located in the Post study branch of the
Project Tree.
Structural linear superposition
supports all post processing options supported by structural linear
analysis. Thermal linear superposition supports all post processing options
supported by thermal analysis.
