Hi there,
My task is generating a list of all edges in mesh. (ps. I mean not edges of geometry, i saw some function there, which shows edges of a geometry, they are performed bases on interacting between mesh and geometry.)
For a mesh i can easily get access to elements (3d : tetraeder). I am considering break down each element into four faces. It’s easy for me to get edges from faces (2nd step).
(elements -> faces -> edges)
now the problem is in 1st step. A 3d quadratic case, that means an element consists of ten nodes. I have no idea which node is vertices which is in middle of edges.
The way to create mesh :
cubic = [100, 50, 20];
model = createpde(thermal="transient");
geo = multicuboid(cubic(1), cubic(2),…
cubic(3), ‘Zoffset’, 0);
model.Geometry = geo;
generateMesh(model, GeometricOrder=’quadratic’);
pdemesh(model)
Is there any tips for me?
Thank you all.

Best regards
