Each optimization task is based on one or more finite element
analysis models. These models form the basis for the optimization, that is,
contain the nodes or elements to be changed and the loads and boundary
conditions for the calculation of important terms for the optimization.
Further, node and element groups or coordinate systems in the analysis
files are available for further definitions in the optimization task.
Additional files might contain objects for the definition of constraints
or provide supplementary analysis results to be considered in the optimization.
This chapter deals with requirements for optimizable models and discusses
the loading of models. Further, the definition of groups and coordinate
systems in your optimization environment is explained.
