Programming mesh connectivity
 

Hello,

I was wondering, how to implement mesh connectivity or element ID into a meshing program, to check wether the element is an interior or boundary cell or even more important how many faces of the element are connected to a boundary wall.

Is there s popular way of doing this ?
Would appreciate any hints, or eventually exemplary code.

Thanks for any help!

Found a good way in the book "The Finite Volume Method in Computational Fluid Dynamics" by Moukalled.
