[Libmesh-users] flat subdomain boundary

[Chang, H. <mo...@nf...>]

Hi,



Now I try to solve Poisson's equation for the electrostatic field and continuity equations for plasma fluids in the same mesh.



In this case, dielectric region has to be included in Poisson solve, but not in continuity equations.



In LIBMESH example, I found that subdomain method make it possible to determine whether included or not.



I'd like to ask about how can I make flat the uneven boundaries between two different domains.



Not only is it not good to look at but it also presents difficulties in correcting errors in boundary conditions.
