About SeStructures

Ian Rivard

Structural analyst and founder of SeStructures LLC. Ian's work is finite element analysis of aerospace structures — spacecraft and payload structures, aircraft components and installations, and the modifications and repairs that keep fleets flying — in FEMAP with NX/Simcenter Nastran and MSC Nastran.

Most of that work is shell models: idealizing solid CAD into shell models that are simple enough to run and iterate, and accurate enough to defend. Every one of them is checked against a solid mesh of the same geometry, which is both a habit and the reason the Shell Mesh Service exists.

Ian is a co-author of Engineering Tools, a free, open-source suite of FEMAP/Nastran productivity tools used by the FEMAP/Nastran community, and he contributes FEMAP API scripts to the community under the SeStructures name. The same philosophy runs through the consulting: give the repetitive work to the computer, keep the judgement with the engineer.

Working with us

• One point of contact from scoping to delivery; no hand-offs to a bench you have not met.
• Fixed-scope quotes where the scope is clear; hourly support when you need an analyst on call.
• Remote by default, from Sarasota, Florida.
• Your data stays yours: uploads through the secure file drop, an NDA on request, and nothing client-identifying ever appears on this site.
