Who is using adaptive mesh refinement? We are using local mesh refinement, and I believe this is a desireable feature for many users. Maybe I'm wrong? I do not think we should brake the local mesh refinement algorithms. At least there should then be the option of using the old mesh library until the local mesh refinement is in place in the new mesh format. If no one else is interested in this feature I will implement these algorithms. It would fit well with our activity in other mesh modification algorithms. But I still think the option of using the old mesh should be there, instead of breaking the local mesh refinement capability. /Johan > > /Anders > _______________________________________________ > DOLFIN-dev mailing list > DOLFIN-dev@xxxxxxxxxx > http://www.fenics.org/mailman/listinfo/dolfin-dev >
