Create Envelope of Results

Identify the most significant result out of all selected analyses.

Before you begin, you must have one or more structural linear or multi-loadcase analysis results in the design study.

Envelope can be either max, min, or extreme. Envelope is mathemetically represented by the following equation for each point:

$\{R_{s}\} = (min/max/extreme) \{c_{1} \{R_{1}\}, c_{2} \{R_{2}\}, \dots c_{i} \{R_{i}\}\}$

Where,

$R_{i}$: A vector of results (displacements, stresses, strains, and so on) for each individual load case.
$c_{i}$: Scale factor.
min: Finds the minimum value among all the selected analyses weighted by appropriate scale factors.
max: Finds the maximum value among all the selected analyses weighted by appropriate scale factors.
extreme: Finds absolute maximum value among all the selected analyses weighted by appropriate scale factors. The sign of the number is not changed during result display. For example, extreme of 5 and -10 is -10.

On the main toolbar, select (Post study).
Select Structural envelope.
From the drop-down menu, select the type of envelope analysis.
In the dialog, hold down Control + Shift and select the results to combine.
Click the button to combine analyses.
Click Solve.
Structural envelope supports Results plot and Pick info post processing options.
