question about lattice generation and related FEA result
Hello
I see that the Inspire have the very powerful lattice generation function, but since the exported model is stl file, which cannot be editable by other FEA software to double check. Since the project required high accuracy with the FEA result based on lattice generated model, is there any documentation, or related stuff is able to explain some basic theory about the calculation method of the FEA result based on stl lattice model, and is there any way to export the file as parasoid or acis format?
thank you

You should be able to save the geometry (polynurbs) from the lattice optimization as an ACIS or parasolid as well as a few other options.
The options for these optimization within Inspire can be found at https://2021.help.altair.com/2021.2/inspire/en_us/topics/inspire/structure/optimization_lattice.htm?hl=lattice .
As for the theory, Inspire is calling OptiStruct in the background to perform the calculations. The theory of these calculations can be found at the OptiStruct documentation.
