Here is the caller graph for this function:

void P0_CouplingAssembler::assembly

(

const DHCellAccessor &

dh_cell_master

)

Works well but there is large error next to the boundary.

TODO:

• pass through the master and all slaves and collect global dofs , bcd, solution. I.e. call Nx pressure_diff not NxNx.
• Is it safe to have duplicate rows in local_system?
• Is it better to have more smaller local system then single big one?

• use one big or more smaller local systems to set.

  ?? How to deal with anisotropy ?? 3d-2d : compute nv of 2d triangle 2d-2d : interpret as 2d-1d-2d, should be symmetric master-slave 2d-1d : nv is tangent to 2d and normal to 1d arma::dot(data_->anisotropy.value( ele_centre, ele->element_accessor())*nv, nv)
