3. Introduction
 Finite Element Analysis (FEA) is a very good tool for providing useful
insight into stresses and deformations which in turn the engineer can
assess the strength and durability of mechanical components and
large structures.
 These days FEA tools are often integrated into the CAD platform
which makes anyone and everyone without a working knowledge in
FEA can perform complex analysis.
 But by keeping in mind the few things can help you verify if the results
are reliable to make the big change in design –

4. Most designers know how the component will look like under loading. Is the
deformation happening in the right plane?
Or is the deformation obtained is insanely high like 1 meter.
 Check Reaction forces.
 Check FEA software default settings.
 Singularity and Peak Stress values
 Check for Errors and convergence issues
 Model Constraints
 Wrong interpretation of Post-processed results

5. Check Reaction forces:
 Checking the reaction forces helps you to verify if the overall mass
and loads assigned are correct. Do the reaction forces add up and
makes sense, if yes – thumbs up!
Check FEA software default settings:
 Inorder to speed up the process, most FEA tools have automated
contact surface detection algorithm.You have to verify if the
settings assumed by the software are correct to what you are
trying to simulate.
 Always keep this in mind – the software only does what you tell it
do. It does not know what you want it be.

6. Singularity and Peak Stress values:
 Often you see a very high stress a minuscule area, which is called a
peak stress or stress singularity.These are generally due to mesh
skewness and numerical errors. Such stresses cannot be taken at
face value and should be ignored while you make decisions.
Check for Errors and convergence issues:
 Always check the errors tabs which shows any convergence or
negative equation issues.You have to re-check the mesh or
boundary conditions and re-run the simulation.
