Preprocessing of a finite element analysis might be performed
in various preprocessing systems. To be able to use Tosca Structure
in a familiar environment, Tosca Structure
offers several preprocessing interfaces.
The finite element model might be generated in every finite element
preprocessor that can generate an input model for the supported finite
element solvers. Simplifications for the formulation of the optimization
task (such as groups, different properties, ...) might also be defined
in many FE preprocessing systems that are not mentioned below (for example,
Hypermesh). The optimization preprocessing of Tosca Structure
is mainly based on group information. Group definition can be made by graphical selection of nodes and elements
or already in the FE-preprocessor. Using Tosca Structure.gui,
all necessary information such as design nodes or frozen elements should
be defined as groups in the FE-preprocessor. These groups might be read
by Tosca Structure.pre
and then be referenced in the further definitions of the parameter file.
