Ball Grid Array Example bga-30 for the Surface Evolver

[Click for the bga-30.fe datafile in a second window.]

This model takes advantage of radial symmetry to greatly cut down the computational expense of the BGA joint. Instead of a full surface, only one radial cross-section is modeled. Of course, this type of model is no good if you want to find lateral restoring forces, but it is a tremendous time and memory saver when it does work.
