Re: [Libmesh-users] inhomogenous dirichlet BCs

[Mauro W. <m_w...@sf...>]

Hi Ataollah,

this type of problem is indeed called a 'contact problem'.  I don't
know how to solve them, neither in libmesh nor otherwise.  Anyways,
here a short recent discussion about it on libmesh-users:

This BC is a bit weird since it doesn't apply to all of the faces of a boundary_id rather it applies to faces within the contact range (changes with time) and all the other faces should have natural (traction free) BCs.
