A focused technical conversation about one decision — not a general introduction and not a sales call. You send the pre-read material beforehand so the session starts with the actual problem rather than with context-setting.
The deliverable is the written output afterwards: a written summary of options with a recommendation and the reasoning. That is yours whether or not you engage Linnea for the follow-on work.
If you do not have all of it, book anyway and say what is missing. Turning up without material is still more useful than guessing at a scope on your own.
7 years delivering stress & sizing and composite structures work for telecom and defense clients. I work to DO-160G and NASA-STD-5001, deliver in ANSYS Fluent and CATIA V5, and hand over a complete, checked document set with a clear design basis so your reviewer or authority can follow every assumption.
