Hi all,

I'm not sure under which topic (help/general) to ask about this matter. It seems to me currently netgen (the mesher) only supports a single nature of BC for a segment (edge/face) where you specify the BC for the segment with -bc=n (integer).

As an example, suppose I'm solving a thermo-electric problem where the BC could be for temperature T and voltage potential U. It would nice to be able to do -bc=m,n where m = BC(T) and n=BC(U).

My planned workaround is to use -bc=mn where I have to code in my solver to parse the digits into two types of information (BCs). I'm just wondering if there's already an established method in netgen to handle/specify a BCs for multiple natures/physics modes for a single boundary segment.

Thanks much
