Nice idea! Thanks! It looks like meshtool already does the former (with the -b option) but I hadn't thought about tricking it into doing the latter. I'll commit that to the SVN version once I'm sure I've got it working. Anyone think the "meshbcid" setting tool is worth adding to src/apps too? It's pretty trivial; for example run: meshbcid --mesh me.xda --minpointy 1.0 --maxpointy 2.0 --maxnormalx -0.3 --id 2 Then, whenever it sees a boundary face whose centroid is in the range 1.0 < y < 2.0 and whose unit normal vector has x component < -0.3, it sets that boundary id to 2. --- Roy ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
