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.

VALUE

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.
