No. I'm the one it'd be easy for, but I'm already behind on other urgent things, so not sure when I'll get to it. > Will this also work for the new vector_fe stuff? It should - Paul already took care of all the hard bits when he got vector Dirichlet boundaries working. > I am currently using the displacements (u,v,w) as primary variables and > want to switch to using the nodes position (x,y,z) as primary variables. That's certainly a good reason to want vector PBCs with offsets. If you want to try and speed up the works: write a patch with the API and test case yourself (i.e. give PeriodicBoundary similar functors to DirichletBoundary, add a new vector_fe example using them) and I'll find it slightly easier and much more motivating to see if I can get the implementation passing that test this weekend. --- Roy ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
