3.1.5: Activate Element

The activation state of an element can be controlled with the “Activate Element”-component (see fig. 3.1.5.1). This component expects a model and a list of boolean values as input. The list of true/false values will be mapped to the activation status of the elements in the model. “True” corresponds to active, “False” to inactive. Section 3.5.9 shows, how the “Activate Element”-component enables one to view the solution history of the iterative “BESO for Beams”-algorithm.

Karamba3D sets elements inactive by giving them a very weak material with zero weight.
