# 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.  We next take a look at

 $\sigma_x$

variation in the model. We interrogate

 $\sigma_x$

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
