This document discusses using different finite element analysis modeling methods for the same assembly to verify results. It presents CAD models and material properties, then shows displacement and stress results for the assembly using different element types including hex, tet, shell, and solid elements. The maximum displacement and stress values are documented for each element type modeling method. The conclusion is that the objective of comparing results from different FEA modeling methods is achieved.

- 5. ? Verification of FEA results by use of deferent FEA modeling methods with same element pattern and assembly method with same load and boundary condition(inertia relief) . ? It is a exercise of use of deferent testing methods and what type of assembly will satisfy it in all respect.

- 28. ? The objective is achieved by getting different results from assembly by use of deferent modeling methods without change of base pattern of FEA model. ? Same assembly has to go for dynamic inertia relief test to gather output results variation.
