To Perform the Test:
The articulated_truss.CATAnalysis document presents a
complete analysis of this case, computed with a mesh formed of beam
elements.
To compute the case, proceed as
follow:
-
Open the CATAnalysis document.
-
Compute the case in the Generative Structural
Analysis workbench.
-
Create local sensors
(Displacements vectors).
