RBDO
Set up a reliability-based optimization (RBDO) and execution by defining objective of decoupling rigid body modes, creating constraints for rigid body mode frequencies and specifying design space for variables in terms of mount stiffness, locations, and inclinations.
Specify a design space for design variables. It can be set from nominal values or optimized values from a deterministic optimization run.
