# Numerical Results

The following video shows how to plot the deformed shape and use it to check if the displacement constraints have been applied correctly.

variation in the model. We interrogate

variation in the interior of the model using a plane.

# Verification and Validation

• Check that the solution agrees with the mathematical model

• Are the boundary conditions on displacement and traction satisfied?

• Is equilibrium satisfied?

• Do the reaction forces balance the applied load?

• Check that the numerical error is acceptable

• Are the ANSYS results reasonably independent of the mesh?

• We can refine the mesh by reducing the Size Controls and updating the solution.  We can then compare the results to the original mesh.

• Compare with hand calculations for the bending stress and maximum displacement
