Technically - yes, I'm told people have done it, and there's nothing in the library that's really incompatible with any contact formulations. Practically, your application code would have to deal with a few issues to worry about that we don't cover in any of the examples and that we don't provide decent in-library APIs for. Identifying contact patches efficiently probably requires a more sophisticated algorithm than our PointLocator octrees, and you'd need to add Jacobian sparsity pattern entries by hand if you're trying to do an implicit formulation. --- Roy ------------------------------------------------------------------------------ AppSumo Presents a FREE Video for the SourceForge Community by Eric Ries, the creator of the Lean Startup Methodology on "Lean Startup Secrets Revealed."
