[Libmesh-users] Novice question - how do I check which boundary_id value for which boundary?

[Yuxiang W. <yw...@vi...>]

Dear all,

Sorry for the spam.

In system_of_equations_ex6.C, the example recognized which boundary is
which by knowing the values for MIN_Z is 0, MIN_Y is 1, etc. to apply all
sorts of boundary conditions. I wonder could anyone share with me a
reference to find out how would I know which number is which boundary? I
tried to export the mesh into EXO & UNV format, inspected with ParaView but
the boundary id does not really get mentioned in those files.

I'd really appreciate any tips. Thank you!

Best,
Shawn
