All the machinery is there in the sense that you can already evaluate shape functions on boundaries (as in BC assembly), but you'd need to be able to add a "boundary-only variable" to have the correct number of degrees of freedom for the 1D variable. Maybe this could be implemented similarly to the "subdomain-only variables"? > > At Wed, 8 Feb 2012 22:07:16 +0000, > Sylvain Vallaghe wrote: >> Hi, >> >> I'm trying to implement a 2d problem in libmesh where I have two scalar >> variables : one is 2d in the whole domain, the other is 1d and mapped on one >> of the boundaries of my domain.
