DirichletBoundary objects currently work based on boundary IDs. I'd like to be able to use DirichletBoundary objects to impose boundary conditions on boundary nodes and/or edges of a mesh.
The motivation is to use Node or Edge Dirichlet boundary conditions to impose boundary conditions in structural analysis that don't constrain rotation (e.g. to provide a simple way to model joints or pins). I guess the target Node or Edge could be identified by passing in multiple boundary IDs and imposing the BC on the nodes or edges that belong to all of those IDs. Would this be workable within the current DirichletBoundary framework (perhaps there are some issues since it presumably uses L2 project on boundaries...) and does this seem like a change of general interest? If so, I'm happy to work on it. Thanks, David ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
