Boundary conditions in TracerModel

[Reza Najafi]

Hi all,

Would you please explain the bc fields required in equationsTracer.m? Are source faces defined as boundary faces in the grid associated with injection or production wells? What if there are no wells, only boundary conditions?

% The boundary condition (bc) term requires the following fields:
% - flux2qextmap : mapping from flux values to flux on external faces
%                  oriented towards the outer domain.
% - flux2qbcmap : mapping from flux values to flux on the source face
%                 oriented towards the outer domain.
% - bc2extmap : mapping from values at source faces to external faces.
% - ext2cellmap : mapping from values at external faces to adjacent cells
%                 (used to compute influx).
% - tracers : concentration of the tracers at the source faces.
