Buckling Optimization of a Structural Rail - OS-5030 
Bulk Data Section 
Can I combine various optimization types (size with shape and/or topography? 
Can I export the DVGRID information from a topography optimization? 
Can I use buckling constraints on a topology or free-size optimization? 
Can I use stress constraints with topology or free-size optimization? 
Can OptiStruct use more memory than I have actually installed on my system (i.e. more than installed RAM)? 
Can volume or mass be defined as a response for topography optimization?
