I would like to get a pretty accurate method to do finite element analysis (FEA) on my 3d designs considering the infill. I use Autodesk Inventor to design parts but the FEA can only be applied to a solid body (100% infill). Does anyone know software that can convert a 3d design to another but considering the infill so I can use FEA more accurately?

Rhino will let you create a custom lattice structure inside the solid object, this can in turn be used to create infill using grasshopper (an inbuilt scripting tool):

  • create a standard cell size and apply the lattice,
  • convert the whole thing to solid,
  • reimport into inventor
