The idealization and assumptions made while designing the structure.
Checking the orientation and the cross-section of the beams that are defined
in the structure and to also ensure the assignment of correct thicknesses
for different components.
Check for any overlapping nodes or elements are present in the model.
Check to see if the mass allocated to every component matches the
experimental model.
Check that all the loading and boundary conditions are applied at the
correct locations.
Run an element quality check in HyperMesh to see
if all the elements are within the acceptable criteria.
Check the consistency of the element local direction.

FEM Validation
A few ways to validate an FEA model are:
Experimental test
The results from FEA can be compared to the experimental
tests performed under similar loading conditions.
Comparing with existing documents
The results from FEA can be compared to
the results obtained from similar benchmarked models. The model can also
be compared against established guidelines.
Comparing with classic solution
The results from FEA can be compared with
classical solutions. The model can also be compared against established
guidelines.
