Theoretical Background of SimSolid by Victor Apanovitch

GirishM

The SimSolid computational engine is based on extension to the theory of external approximations. External approximations are a generalization of Finite Element Method (FEM) in terms that:

• Absolutely arbitrary geometrical shapes can be used as “finite elements”.
• Basis functions which approximate the field of interest in the “element” can be of arbitrary class and are independent of the “element” shape.
• The degrees of freedom are integrals over corresponding geometrical entities.
• Multi-pass adaptive analysis to control the solution accuracy.

Thanks Victor. Still too complicated for most people probably. I like the slides on the boundary condition implementation here and how it is approximate in SimSolid.
