[petsc-dev] DMPlexAddBoundary

[Adrian Croucher]

hi

I'm trying (and so far failing) to understand how the locations for 
setting boundary conditions are defined in the TS ex11 example.

In the 'PhysicsCreate' functions there are calls to DMPlexAddBoundary(), 
which takes an array of IDs; e.g. in PhysicsCreate_SW() the IDs are 
{100,101,200,300}. It looks like these IDs define where the BCs are 
applied, but what do these numbers actually refer to?

Thanks!

Cheers, Adrian
