A student is trying to setup a simple contact problem for an exercise. The exercise asked them to model a steel ball with a vertical load that comes in contact with an aluminium block. They have chosen to work in 3D and the problem is setup as shown in the figure. Describe the following. What is evidently wrong in this setup by looking at the image? Why setting this problem in 3D is not the most efficient way to solve it? What is the most efficient way to setup a problem like this and what would be the main difference from the current setup? 0.02 0.02 0 -0.02 E -0.02 0.03 0.02 0.01 m 0 -0.01 A student is trying to setup a simple contact problem for an exercise.
