Automated Topology Optimization Generation (ATOG). A value between 0 and 8 defines one of the predefined topology design optimization solutions generated. There are eight options: 0 - Automated topology optimization generation is disabled. 1 - The objective is minimize compliance, the design constraint is volume fraction (mass fraction), and the solution is linear statics. 2 - The objective is minimize volume fraction (mass fraction), the design constraints are stress and compliance index, and the solution is linear statics. 3 - The objective is minimize volume fraction (mass fraction), the design constraint is maximum displacement and compliance index, and the solution is linear statics. 4 - The objective is minimize volume fraction (mass fraction), the design constraint is maximum singe point constraint force and compliance index, and the solution is linear statics. 5 - The objective is minimize volume fraction (mass fraction), the design constraint is compliance index, and the solution is linear statics. 6 - The objective is minimize volume fraction (mass fraction), the design constraint is modal frequency, and the solution is normal modes. The character variables: DISABLE, COMPVF, VFSTRESS, VFDISP, VFSPCF, VFCOMP, AND VFFREQ may be used in place of the numerical options 0 through 6. All objectives are minimized and all constraints are upper limits except for modal frequency which is a lower frequency limit. Multiple subcases are supported and applicable to all constraints.
