These values are saved in a solver result file, or, for visualization reasons, in vtfx files by the component Tosca Structure.report. Further, smoothed results can also be processed in vtfx format. Shape and bead optimizations result in displacements of the nodes in the design area. In this case, too, Tosca Structure.report produces vtfx files containing the model with these displacements. In addition to the optimization displacements, it is possible to write the controller input values from controller-based shape or bead optimization to the output file in vtfx format for visualization. Sizing optimization modifies the shell thicknesses in the model. Tosca Structure.report produces vtfx files containing the model with the modified shell thicknesses as well as the shell thickness changes as a contour plot. Morphing creates similar to shape optimization models with displaced nodes. Tosca Structure.report produces vtfx files containing the model with these displacements for each morphing step. In addition to the optimization displacements, it is possible to write the controller input values from the assigned shape optimization task. In addition, optimization relevant values (scalar values of objective or constraint) and all design responses or variables defined in the optimization job will be available in an history plot in the vtfx report. Note that conversion or variables defined in the optimization job will be available in a of optimization results to solver formats is no longer available.
