Analyse a part
Typical run: 1–5 minutes. You will get an e-mail with a private link to the interactive report. The link is unguessable and acts as the password: anyone you share it with can view the part and the result. Result pages expire after 7 days. Interactive viewing only, no file downloads.
Your geometry: the uploaded CAD is kept by SeStructures LLC to develop and validate this service; it is not shared or published. Meshes, solver files and intermediate results are deleted as soon as the report is built. Do not upload export-controlled or third-party-confidential geometry.
What you get
- Free-free normal modes of the part (10-node tetrahedral mesh, MYSTRAN SOL 103, 12 flexible modes) in an animated 3D viewer.
- Mode identification by energy — element strain energy (ESE) and kinetic energy (EKE) per region per mode, the method behind the Engineering Tools Mode Identification macro, with regions found automatically.
- Cumulative strain-energy hot spots — the few elements that carry half of each mode's strain energy, and the core zone shared by the first modes (Engineering Tools Group Elements by Cumulative Strain Energy Participation).
- Stiffen / lighten advice — first-order sensitivities of the natural frequencies to adding or removing material in each region: where a gram of material buys the most stiffness, and where mass is just riding along.
Limits of this prototype: one isotropic material, no supports or loads (free-free), first-order sensitivities, mesh capped for run time. Shell-model services (midsurface idealization, shell-vs-solid checks) are next.
