It'd actually be pretty easy now that the heterogenous constraints are in - we'd just want to add "offset" values to the PeriodicBoundary class and respect that when constructing the constraint equations. The main problem is: isn't the new PBC code still failing some of your tests? Last I heard, John still had a MOOSE regression test breaking but hadn't been able to distill it down into a libMesh-only failure case to send me. --- 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.
