Dear everyone,
I need to solve let's say the heat equation over a domain made of two
different bodies. The heat flux must be discontinuous at the interface
between the two bodies. I guess I have the following options:
- Generate a mesh where the interface is explicitly meshed. I am used
to GMSH, which does not deal very well with hexas. Is there any good
hexa mesher that you would advice?
- Generate a regular mesh and then "cut" it along the interface. I
have seen such work for tetras, but I am not really sure it is even
possible for hexas... Is there any good hexa mesh modification tool that
you would advice?
- I am used to the extended finite element method where one enriches
the approximation space of the elements cut by the interface by
introducing additional degrees of freedom in order to capture the
discontinuity without any need for remeshing. Is there such or
comparable possibility inside deal.II?
Thanks in advance for your help,
I am really looking forward being part of the deal.II community.
Martin.
