Each analysis case has over 60 warnings. Most warnings are about
tolerance calculations for contact interactions, because you did not enter a
tolerance when you created the interactions. However, the default tolerance is
suitable for this example.
Contact can be a complex and error-prone area in
simulations. In practice, verify that you have not accidentally specified
contact between surfaces that are not intended to be in contact. Also,
verify that you included all surfaces that are required to be in contact
with each other.
