Finite element analysts and designers need to feel confident in the results of their
analyses before sending a product to prototype or production. Mesh discretization can
greatly influence the desired results. In this paper we present framework for adaptive
mesh refinement to obtain FEA results with a desired accuracy. The process involves
adaptively refining the mesh based on solution error norms until the result desired
converges to certain accuracy. The adaptive refinement/meshing process must be fully
automatic and very robust. We present an exhaustive method to create a fully automatic
and integrated process that takes advantage of many of the mesh refinement and mesh
optimization algorithms found in literature. The results of the process provide the
user with the desired accuracy in the smallest number of iterations
