Why are these best practices important?
• Contact is the most common source of nonlinearity and is often the
most difficulty to solve!
• With typical structural problems, the presence of nonlinear contact can
often be the biggest reason for increased solution times.
• Poorly defined contact may lead to unstable contact conditions. These
conditions usually mean bad convergence and lost time.
• With ideal contact conditions, contact results converge much more
quickly and the results tend to be smoother.
