The “DisassembleModel”-component can be used for decomposing a structural model into its components (see fig. 184.108.40.206). Resulting loads, supports and elements reference the nodes they connect to by position – regardless whether they were initially defined using coordinates or node-indexes. This allows to reuse parts of an old model and reassemble them in a new model where the node indexes have changed. At the “CroSec”- and “Material”-output only those cross sections and materials show up which were directly fed into the “Assemble”-component. In order to get all cross sections, it is necessary to disassemble the model elements. The cross section materials result from disassembling the cross sections.
