The demo shows how to:
Extract and visualize modal effective mass (including residual vectors) and use Miles equations for early-phase random vibration estimates.
Use the Energy Processor (strain energy by group) to pinpoint which panels, struts, or substructures are really driving problematic modes, guiding where to stiffen or lighten your design.
Apply the Stress Processor to build envelopes across many static/dynamic load cases and automatically compute margins of safety, writing them back into reduced OP2 files for easy plotting in Femap.
Handle very large models and OP2 files (millions of nodes, 1 TB+) by setting proper thresholds (e.g., PARAM,TINY) and grouping strategies.
Along the way, Frédéric shares practical tips on workflow setup in SATK V11 and what V12 improves (shared materials, reusable groups and stress cases), plus rules of thumb for damping, effective mass targets, and when to use residual vectors.
This video is a great preface for anyone who already uses SATK for random/sine and wants to turn it into a full structural correlation, energy, and margin-of-safety environment rather than just a PSD post-processor.
