2 Let's say I create a .poly detailing the information of the my domain geometry. I also add node boundary markers and face boundary markers. Question 1 : Do I have to be consistent between the boundary markers of nodes and faces? I mean, if a node belongs to a face with boundary marker 1, do I have to label it with 1 too? Question 2 : In the case there's no need to be consistent, what will happen when I create the mesh? Specifically talking, which boundary markers will appear in .face and .node files? The boundary markers of the faces or the nodes specified in the .poly file? How should I proceed to propagate the boundary markers in a good way (I'm doing Finite element method, so I want to know which are my Dirichlet and Neumann faces)? finite-element-analysis tetgen share | improve this question edited Nov 10 at 17:57 asked Nov 10 at 5:43 Gonzalo Benavides 118 6 add a comment  |  2 Let...

It also acquired a reputation for the war crimes (such as the massacre of more than 30,000 Jews at Babi Yar in September 1941) that it committed under the command of Field Marshal Walther von Reichenau during Operation Barbaro...
