Setup an optimization solver deck to get solution proposals.
Solving any engineering problem using simulation can be done in two ways; iterative
changes until reaching a solution or using Optimization. The objective of the
Optimization feature in SnRD is to seamlessly setup an
optimization run based on analysis performed in the post processing and sensitivity
analysis steps.
The objective is to reduce the relative displacement between selected components
targeting the most contributing mode(s) identified during the diagnosis phase.
Two optimization methods are supported in SnRD:
Topology Optimization: Systematic problems
Free Size Optimization: Non Systematic problems

Frequency Response (MFREQ)
