The ANSYS Conference Proceedings of 1989 had a very good paper by J.C.Anker
- ''Ordering, Monitoring, Reviewing and Accepting a Finite Element
Analysis'', which I used as a first pass at creating a checklist for FE
users. The details are perhaps not there for an analyst, but the philosophy
is sound and I would recommend it.

> Checklist for FEA Analysis

> 1. Matching model units (State units in the analysis title for
> reference)
> Geometry, material properties, applied loads

> 2. Element type (proper application of type, keyopt switches)

> 3. Consistent normals for shell and the new 3D contact
> elements(170-174).

> 4. Gaps (proper orientation)

> 5. Real constants (correct real number assigned and correct values)

> 6. Material number and element type numbers (set correctly)

> 7. Elements and nodes are all selected

> 8. Duplicate nodes or elements

> 9. Cracks or missing elements

> 10. Planes of symmetry and symmetric boundary conditions.
> Torque is an anti-symmetric condition
> 1/2 load at symmetric boundary
> Pressures are calculated over whole surface

> 11. Loads, couplings and constraints (Nodal rotation, units check)

> 12. Angles & rotational velocities in radians.

> 13. Coordinate systems (is the proper one active)

> 14. Method of verification of results (hand calculations, test data)
> Check for balanced reaction forces
