Workshop 2a
Nonlinear Contact Analysis of a Cell Phone Antenna Snap Fit

In this workshop the student uses a nonlinear contact solution with friction to simulate a cell phone antenna snap fit problem. The problem initially does not converge, and the student adjusts nonlinear model parameters to make it converge. The model then gives incorrect answers, and the student resolves that problem. The student also uses a commands object to control whether the symmetric or unsymmetric solver is used in order to improve solution performance.
