Extract the boundary mesh 2. Create a new mesh which is has both topological and geometric dimension 2. 3. Manually build the 2D mesh by copying data over from the boundary mesh. Use a MeshEditor for 2 and 3. -- Anders -- You received this question notification because you are a member of DOLFIN Team, which is an answer contact for DOLFIN. _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : [email protected] Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
